+ Move creation of 'this' object from caller to callee in construction.
+
+ Presently the caller of a constructor is responsible for providing a this
+ object. Instead, move the object creation into a new op_create_this opcode,
+ planted in the head of the contructor bytecode for a function. Since the
+ prototype for the object is provided by performing a get_by_id on the callee,
+ also add a new get_callee opcode (this is used to get the callee JSFunction
+ into a register so that a normal get_by_id can be used).
+
+ Currently the caller is also responsible for detecting when op_construct is
+ performed on a JSFunction representing a host function, in which case an
+ exception is thrown – and this check currently takes place when constructing
+ the this object. Instead, mirroring the recent changes for non-host functions,
+ add a parallel code-path for native constructors to follow, with a thunk for
+ invoking native constructors provided by JITStubs, and a constructor-specific
+ NativeFunction on NativeExecutable. Provide an implementation of a host
+ constructor which will throw an exception.

+ All callable objects should have a global object reference
+ https://bugs.webkit.org/show_bug.cgi?id=39495
+
+ All objects that may ever return a value other CallTypeNone
+ or ConstructTypeNone now get a global object in their constructor
+ and store that in their first anonymous slot. We add a new type
+ JSObjectWithGlobalObject to allow us to share this logic as much
+ as possible, however some objects have specific inheritance
+ requirements so we can't just use it universally.
+
+ To enforce this requirement JSValue::getCallData and getConstructData
+ make use of a new "isValidCallee" function to assert that any object
+ that returns a value other than CallType/ConstructTypeNone has a
+ global object in anonymous slot 0.
+
+ In order to ensure that static function slots are converted into
+ function objects with the correct global object, all prototype objects
+ and other classes with static function slots also gain a global object
+ reference. Happily this fixes the long standing issue where host
+ function objects get a prototype from the lexical global object of the
+ first function that calls them, instead of the global object that they
+ are defined on.

+
+ Bug 39408 - Unify JIT/interpreter return behaviour.
+
+ Presently the JIT and the interpreter have differing implementations in how
+ they handle storing the result of a function call back to the register file.
+ In both cases the op_call ( / _eval / _varargs / op_construct) opcode has an
+ operand indicating the VM register in which the result should be stored.
+ The JIT plants code after the call to store the result, so the value will be
+ stored as soon as the callee has returned. In the interpreter the call
+ passes the return value register id into the callee via the callee callframe,
+ and the callee is responsible for writing the result back into its callers
+ register file after it has restored the parents callframe pointer, but before
+ returning.
+
+ Instead, move the task of writing the call result to the register file into a
+ new opcode (op_call_put_result), and after returning the callee should leave
+ the return value in a canonical location. In the case of the interpreter,
+ this canonical location is a local variable in privateExecute
+ (functionReturnValue), in the case of the JIT this is the normal return value
+ registers (regT0, or regT1:regT0 in JSVALUE32_64). op_call_put_result stores
+ the result from the canonical location to the registerfile.
+
+ In addition to unifying JIT & interpreter behaviour this change allows us to
+ remove a slot from the callframe, omit the write of the result where the
+ return value from the call is not used, and provides a 2% speedup on sunspider
+ in the interpreter.

+
+ In r59162 a change was made to WebCore's FeatureDefines.xcconfig that enabled FILE_READER and FILE_WRITER.
+ The author and reviewer of that patch ignored the carefully-worded warning at the top of that file asking
+ that changes to the file be kept in sync across JavaScriptCore, WebCore and WebKit, as well as being kept
+ in sync with build-webkit. This led to WebCore and WebKit having different views of Document's vtable
+ and results in crashes in Safari shortly after launch when virtual function calls resulted in the wrong
+ function in WebCore being called.
+
+ We fix this by bringing the FeatureDefines.xcconfig files in to sync. Based on the ChangeLog message and

+
+ The URLParser has a couple calls to ASSERT(), which I've commented out

+
+ Also, there are a number of methods that are declared public in this

+ Bug 38604 - workers-gc2 crashing on Qt
+
+ This appears to be due to a couple of issues.
+ (1) When the atomic string table is deleted it does not clear the 'inTable' bit
+ on AtomicStrings - it implicitly assumes that all AtomicStrings have already
+ been deleted at this point (otherwise they will crash in their destructor when
+ they try to remove themselves from the atomic string table).
+ (2) We don't fix the ordering in which WTF::WTFThreadData and
+ WebCore::ThreadGlobalData are destructed.
+
+ We should make sure that ThreadGlobalData is cleaned up before worker threads
+ terminate and WTF::WTFThreadData is destroyed, and we should clear the inTable
+ bit of members on atomic string table destruction.
+
+ WTF changes (fix issue 1, above) - ensure inTable property is cleared when the
+ atomic string table is destroyed (also, rename InTable to IsAtomic, to make it
+ clear which table we are refering to!)

+ Need to support more efficient dispatch of lightweight builtins
+ https://bugs.webkit.org/show_bug.cgi?id=38155
+
+ The problem with calling lightweight builtins is that marshalling
+ the call from the nitro calling convention to the system calling
+ convention is very expensive relative to the cost of the actually
+ evaluating the function. To work around this problem this patch
+ adds the ability to define a custom thunk for a builtin.
+
+ This allows us to use high performance custom implementations of
+ the common and sensible versions of simple builtins. This patch
+ includes a simple (use of which is currently hardcoded) thunk for
+ charCodeAt.
+
+ This adds a JSInterfaceJIT subclass called SpecializedThunkJIT
+ that has helper functions to remove (or at least reduce) the need
+ to have separate thunk implementations for each JSValue encoding.

+ Bug 36519 - JSGlobalContextRelease is unnecessarily slow
+
+ Since [ http://trac.webkit.org/changeset/35917 ], calling
+ JSGlobalContextRelease always triggers a GC heap collection
+ (if not a full destroy). As per 35917's changelog "This is
+ only really necessary when the (JSGlobalObject's) last
+ reference is released, but there is no way to determine that,
+ and no harm in collecting slightly more often."
+
+ Well, we now know of cases of API clients who are harmed by
+ the performance penalty of collecting too often, so it's time
+ to add a way to determine whether a call to JSGlobalContextRelease
+ is removing the last protect from it's global object. If further
+ protects are retaining the global object (likely from other
+ JSGlobalContextRefs), then don't trigger a GC collection.
+
+ * API/JSContextRef.cpp:

+ Bug 35537 - put_by_id does will incorrectly cache writes where a specific value exists,
+ where at the point of caching the same value is being written.
+
+ When performing a put_by_id that is replacing a property already present on the object,
+ there are three interesting cases regarding the state of the specific value:
+
+ (1) No specific value set - nothing to do, leave the structure in it's current state,
+ can cache.
+ (2) A specific value was set, the new put is not of a specified value (i.e. function),
+ or is of a different specific value - in these cases we need to perform a despecifying
+ transition to clear the specific value in the structure, but having done so this is a
+ normal property so as such we can again cache normally.
+ (3) A specific value was set, and we are overwriting with the same value - in these cases
+ leave the structure unchanged, but since a specific value is set we cannot cache this
+ put (we would need the JIT to dynamically check the value being written matched).
+
+ Unfortunately, the current behaviour does not match this. the checks for a specific value
+ being present & the value matching are combined in such a way that in case (2), above we
+ will unnecessarily prevent the transition being cached, but in case (3) we will incorrectly
+ fail to prevent caching.
+
+ The bug exposes itself if multiple puts of the same specific value are performed to a
+ property, and erroneously the put is allowed to be cached by the JIT. Method checks may be
+ generated caching calls of this structure. Subsequent puts performed from JIT code may
+ write different values without triggering a despecify transition, and as such cached method
+ checks will continue to pass, despite the value having changed.

+ https://bugs.webkit.org/show_bug.cgi?id=35398
+
+ JSPropertyNameIterator and Structure have a cyclic dependency that they
+ manage by clearing the appropriate reference in each other during their
+ destruction. However if the Structure is destroyed while the
+ JSPropertyNameIterator is dead but not yet finalized the Structures
+ WeakGCPtr will return null, and so prevent Structure from clearing
+ the m_cachedStructure pointer of the iterator. When the iterator is
+ then finalised the m_cachedStructure is invalid, and the attempt to
+ clear the structures back reference fails.
+
+ To fix this we simply make JSPropertyNameIterator keep the Structure
+ alive, using the weak pointer to break the ref cycle.
+
+ * runtime/JSPropertyNameIterator.cpp:
+ (JSC::JSPropertyNameIterator::~JSPropertyNameIterator):
+ The iterator now keeps m_cachedStructure alive itself, so no longer needs
+ to check for it being cleared
+ * runtime/JSPropertyNameIterator.h:
+ (JSC::JSPropertyNameIterator::setCachedStructure):
+ Add an assertion to ensure correct usage
+ (JSC::JSPropertyNameIterator::cachedStructure):
+ Add .get()
+ * runtime/Structure.cpp:
+ (JSC::Structure::~Structure):
+ Add an assertion that our iterator isn't already dead, and remove
+ the now unnecessary attempt to clear the ref in the iterator
+ * runtime/WeakGCPtr.h:

+ Leaks tool reports false memory leaks due to Rope implementation.
+
+ A rope is a recursive data structure where each node in the rope holds a set of
+ pointers, each of which may reference either a string (in UStringImpl form) or
+ another rope node. A low bit in each pointer is used to distinguish between
+ rope & string elements, in a fashion similar to the recently-removed

+
+ This allows us to change the rope's fibers to interrogate the object rather
+ than storing a bool within the low bits of the pointer (or in some cases the
+ use of a common parent class removes the need to determine the type at all -
+ there is a common interface to ref or get the length of either ropes or strings).

+ Many false leaks in release builds due to PtrAndFlags
+
+ StructureTransitionTable was effectively a smart pointer type,
+ one machine word in size and wholly contained as a member of
+ of Structure. It either pointed to an actual table, or could
+ be used to describe a single transtion entry without use of a
+ table.
+
+ This, however, worked by using a PtrAndFlags, which is not
+ compatible with the leaks tool. Since there is no clear way to
+ obtain another bit for 'free' here, and since there are bits
+ available up in Structure, merge this functionality back up into
+ Structure. Having this in a separate class was quite clean
+ from an enacapsulation perspective, but this solution doesn't
+ seem to bad - all table access is now intermediated through the
+ Structure::structureTransitionTableFoo methods, keeping the
+ optimization fairly well contained.
+
+ This was the last use of PtrAndFlags, so removing the file too.

+ Make naming & behaviour of UString[Impl] methods more consistent.
+ https://bugs.webkit.org/show_bug.cgi?id=33702
+
+ UString::create() creates a copy of the UChar* passed, but UStringImpl::create() assumes
+ that it should assume ownership of the provided buffer (with UString::createNonCopying()
+ and UStringImpl::createCopying() providing the alternate behaviours). Unify on create()
+ taking a copy of the provided buffer. For non-copying cases, use the name 'adopt', and
+ make this method take a Vector<UChar>&. For cases where non-copying construction was being
+ used, other than from a Vector<UChar>, change the code to allocate the storage along with
+ the UStringImpl using UStringImpl::createUninitialized(). (The adopt() method also more
+ closely matches that of WebCore::StringImpl).
+
+ Also, UString::createUninitialized() and UStringImpl::createUninitialized() have incompatible
+ behaviours, in that the UString form sets the provided UChar* to a null or non-null value to
+ indicate success or failure, but UStringImpl uses the returned PassRefPtr<UStringImpl> to
+ indicate when allocation has failed (potentially leaving the output Char* uninitialized).
+ This is also incompatible with WebCore::StringImpl's behaviour, in that
+ StringImpl::createUninitialized() will CRASH() if unable to allocate. Some uses of
+ createUninitialized() in JSC are unsafe, since they do not test the result for null.
+ UStringImpl's indication is preferable, since we may want a successful call to set the result
+ buffer to 0 (specifically, StringImpl returns 0 for the buffer where createUninitialized()
+ returns the empty string, which seems reasonable to catch bugs early). UString's method
+ cannot support UStringImpl's behaviour directly, since it returns an object rather than a
+ pointer.
+ - remove UString::createUninitialized(), replace with calls to UStringImpl::createUninitialized()
+ - create a UStringImpl::tryCreateUninitialized() form UStringImpl::createUninitialized(),
+ with current behaviour, make createUninitialized() crash on failure to allocate.
+ - make cases in JSC that do not check the result call createUninitialized(), and cases that do
+ check call tryCreateUninitialized().
+
+ Rename computedHash() to existingHash(), to bring this in line wih WebCore::StringImpl.

+ Three quick fixes to UStringImpl.
+ - The destroy() method can be switched back to a normal destructor; since we've switched
+ the way we protect static strings to be using an odd ref-count the destroy() won't abort.
+ - The cost() calculation logic was wrong. If you have multiple JSStrings wrapping substrings
+ of a base string, they would each report the full cost of the base string to the heap.
+ Instead we should only be reporting once for the base string.
+ - Remove the overloaded new operator calling fastMalloc, replace this with a 'using' to pick
+ up the implementation from the parent class.

+ conway benchmark spends half it's time in op_less (jump fusion fails)
+ https://bugs.webkit.org/show_bug.cgi?id=32190
+
+ <1% speedup on SunSpider and V8
+ 2x speedup on "conway" benchmark
+
+ Two optimizations:
+ 1) Improve codegen for logical operators &&, || and ! in a condition context
+
+ When generating code for combinations of &&, || and !, in a
+ condition context (i.e. in an if statement or loop condition), we
+ used to produce a value, and then separately jump based on its
+ truthiness. Now we pass the false and true targets in, and let the
+ logical operators generate jumps directly. This helps in four
+ ways:
+
+ a) Individual clauses of a short-circuit logical operator can now
+ jump directly to the then or else clause of an if statement (or to
+ the top or exit of a loop) instead of jumping to a jump.
+
+ b) It used to be that jump fusion with the condition of the first
+ clause of a logical operator was inhibited, because the register
+ was ref'd to be used later, in the actual condition jump; this no
+ longer happens since a jump straight to the final target is
+ generated directly.
+
+ c) It used to be that jump fusion with the condition of the second
+ clause of a logical operator was inhibited, because there was a
+ jump target right after the second clause and before the actual
+ condition jump. But now it's no longer necessary for the first
+ clause to jump there so jump fusion is not blocked.
+
+ d) We avoid generating excess mov statements in some cases.
+
+ As a concrete example this source:
+
+ if (!((x < q && y < q) || (t < q && z < q))) {
+ // ...
+ }
+
+ Used to generate this bytecode:
+
+ [ 34] less r1, r-15, r-19
+ [ 38] jfalse r1, 7(->45)
+ [ 41] less r1, r-16, r-19
+ [ 45] jtrue r1, 14(->59)
+ [ 48] less r1, r-17, r-19
+ [ 52] jfalse r1, 7(->59)
+ [ 55] less r1, r-18, r-19
+ [ 59] jtrue r1, 17(->76)
+
+ And now generates this bytecode (also taking advantage of the second optimization below):
+
+ [ 34] jnless r-15, r-19, 8(->42)
+ [ 38] jless r-16, r-19, 26(->64)
+ [ 42] jnless r-17, r-19, 8(->50)
+ [ 46] jless r-18, r-19, 18(->64)
+
+ Note the jump fusion and the fact that there's less jump
+ indirection - three of the four jumps go straight to the target
+ clause instead of indirecting through another jump.
+
+ 2) Implement jless opcode to take advantage of the above, since we'll now often generate
+ a less followed by a jtrue where fusion is not forbidden.

+ Part 1/3 of <rdar://problem/7377477> REGRESSION: Many web pages fail to render after interesting script runs in isolated world
+
+ Some clients of the JavaScriptCore API expect to be able to make callbacks over the JSC API,
+ and for this to automagically cause execution to take place in the world associated with the
+ global object associated with the ExecState (JSContextRef) passed. However this is not how
+ things work - the world must be explicitly set within WebCore.
+
+ Making this work just for API calls to evaluate & call will be a far from perfect solution,
+ since direct (non-API) use of JSC still relies on WebCore setting the current world correctly.
+ A better solution would be to make this all work automagically all throughout WebCore, but this
+ will require more refactoring.
+
+ Since the API is in JSC but worlds only exist in WebCore, add callbacks on the JSGlobalData::ClientData
+ to allow it to update the current world on entry/exit via the JSC API. This is temporary duck
+ tape, and should be removed once the current world no longer needs to be explicitly tracked.

+ SNES is too slow
+ https://bugs.webkit.org/show_bug.cgi?id=29534
+
+ The problem was that the emulator used multiple classes with
+ more properties than our dictionary cutoff allowed, this resulted
+ in more or less all critical logic inside the emulator requiring
+ uncached property access.
+
+ Rather than simply bumping the dictionary cutoff, this patch
+ recognises that there are two ways to create a "dictionary"
+ structure. Either by adding a large number of properties, or
+ by removing a property. In the case of adding properties we
+ know all the existing properties will maintain their existing
+ offsets, so we could cache access to those properties, if we
+ know they won't be removed.
+
+ To make this possible, this patch adds the logic required to
+ distinguish a dictionary created by addition from one created
+ by removal. With this logic in place we can now cache access
+ to objects with large numbers of properties.
+
+ SNES performance improved by more than 6x.

+ 3) Improve the efficiency of the asObject and asArray functions

+ 4) Make more callers use the checked asCell and asObject

+ 5) Removed the JSCell::marked function and other GC-related
+ functions because these operations are no longer things that
+ code other than the core GC code needs to do directly. Fixed
+ callers that were calling them.
+
+ * runtime/Collector.cpp:
+ (JSC::Heap::markConservatively): Removed unneeded call to MarkStack::drain.
+ (JSC::Heap::markProtectedObjects): Removed unneeded check of the mark
+ bit and call to MarkStack::drain.
+ (JSC::Heap::collect): Removed unneeded checks of the mark bit and also

+
+ * runtime/JSArray.h:
+ (JSC::asArray): Added an overload for JSCell* and changed the JSValue
+ version to call it. Removed some unneeded casts.
+ (JSC::JSArray::markChildrenDirect): Marked this function inline. It's in
+ a header, and if not marked inline this could lead to linking problems.
+ (JSC::MarkStack::markChildren): Added. This helper function is used by
+ the drain function to avoid repating code. Also added the code here to
+ check fro default mark violations in debug code. If a markChildren
+ function adds something to the mark stack, but the type info claimed
+ hasDefaultMark was true, then we will get an assertion now. Also fixed
+ the assertion about the mark bit to use the Heap function directly
+ because we don't have a JSCell::marked function any more.
+ (JSC::MarkStack::drain): Changed a local variable from "v" to "value",
+ and from "currentCell" to "cell". Changed to call markChildren in two
+ places instead of repeating a chain of if statements twice. Changed
+ code that reads and writes the mark bit to use Heap::isCellMarked and
+ Heap::markCell so we can eliminate the JSCell::marked and
+ JSCell::markCellDirect functions.
+
+ * runtime/JSCell.h: Removed JSCell's markCellDirect and marked member
+ functions. Added a comment explaining that asCell should be deprecated
+ in favor of the JSValue asCell member function.
+ (JSC::MarkStack::append): Added the assertion that catches callers
+ that have set the HasDefaultMark bit incorrectly. Changed
+ code that reads and writes the mark bit to use Heap::isCellMarked and
+ Heap::markCell so we can eliminate the JSCell::marked and
+ JSCell::markCellDirect functions. Moved the overload of
+ MarkStack::append for JSValue here so it can call through to the cell
+ version. The old version had a copy of all the code instead, but that
+ repeated the conversion from JSValue to JSCell* and the check for
+ whether a value is a cell multiple times.
+ (JSC::Structure::markAggregate): Moved this function here to avoid
+ dependencies for Structure.h, since this calls MarkStack::append.
+
+ * runtime/JSObject.cpp:
+ (JSC::JSObject::markChildren): Added code to clear
+ m_isCheckingForDefaultMarkViolation so the marking done by JSObject
+ doesn't trigger the assertion.
+
+ * runtime/JSValue.h: Moved some stray includes that were outside the
+ header guard inside it. Not sure how that happened! Removed the
+ GC-related member functions markChildren, hasChildren, marked, and
+ markDirect.
+
+ * runtime/JSWrapperObject.h: Made markChildren private.
+ (JSC::JSWrapperObject::createStructure): Added. Fixes a bug where the

+
+ * runtime/MarkStack.h: Added m_isCheckingForDefaultMarkViolation and
+ initialized it to false. Moved the append function body from here to
+ JSCell.h. Added a declaration of a private markChildren function used
+ inside the drain function.
+
+ * runtime/SmallStrings.cpp:
+ (JSC::SmallStrings::markChildren): Changed the name and style of this

+
+ * runtime/SmallStrings.h: Changed the name and interface of mark to

+ How many copies of the parameters do you need?
+ https://bugs.webkit.org/show_bug.cgi?id=28701
+
+ The function parameters in JSC get copied a lot - and unnecessarily so.
+
+ Originally this happened due to duplicating FunctionBodyNodes on recompilation,
+ though the problem has been exacerbated by copying the parameters from the
+ original function body onto the executable, then back onto the real body that
+ will be generated (this happens on every function). And this is all made worse
+ since the data structures in question are a little ugly - C style arrays of C++
+ objects containing ref counts, so they need a full copy-construct (rather than
+ a simple memcpy).
+
+ This can all be greatly simplified by just punting the parameters off into
+ their own ref-counted object, and forgoing all the copying.
+
+ ~no performance change, possible slight progression.

+
+ Restructure Executable types so that host functions do not hold a FunctionExecutable.
+ https://bugs.webkit.org/show_bug.cgi?id=28621
+
+ All JSFunction objects have a pointer to an Executable*. This is currently always a
+ FunctionExecutable, however this has a couple of drawbacks. Host functions do not
+ store a range of information that the FunctionExecutable provides (source, name,
+ CodeBlock & information presently held on the FunctionBodyNode).
+
+ [ * nearly all... see below! ]
+
+ Instead, make JSFunctions hold a pointer to an ExecutableBase, move fields specific
+ to JS sourced executable types (source, node) into a new subclass (ScriptExecutable),
+ and create a new NativeExecutable type. We now provide a new method in JSFunction
+ to access & downcast to FunctionExecutable, but in doing so we can make an early
+ check (with an ASSERT) to ensure that the Executable read from a function will only
+ be treated as a FunctionExecutable (and thus the JS sepcific fields will only be
+ accessed) if the JSFunction is not a host function.
+
+ There is one JSFunction that currently does not have an Executable, which is the
+ object created to allow us to read out the vtable pointer. By making this change
+ we can also add a new Executable type fror this object (VPtrHackExecutable).
+ Since this means that really all JSFunctions have an Executable we no longer have
+ to null-check m_executable before us it - particularly in isHostFunction().
+
+ This patch removes CacheableEvalExecutable, since all subclasses of ExecutableBase
+ can now be ref-counted - since both JSFunction holds (and ref-counts) an ExecutableBase
+ that might be a FunctionExecutable or a NativeExecutable. This does now mean that all
+ ProgramExecutables and EvalExecutables (unnecessarily) provide an interface to be
+ ref-counted, however this seems less-bad than host functions unnecessarily providing
+ interface to access non-host specific information.
+
+ The class hierarcy has changed from this:
+
+ - ExecutableBase
+ - ProgramExecutable
+ - EvalExecutable
+ - CacheableEvalExecutable (also RefCounted by multiple-inheritance)
+ - FunctionExecutable (also RefCounted by multiple-inheritance, 'special' FunctionExecutable also used for host functions)
+
+ To this:
+
+ - RefCounted
+ - ExecutableBase
+ - NativeExecutable
+ - VPtrHackExecutable
+ - ScriptExecutable
+ - ProgramExecutable
+ - EvalExecutable
+ - FunctionExecutable
+
+ This patch speeds up sunspidey by a couple of ms (presumably due to the changes to isHostFunction()).

+ The method check optimisation made transitions aware of the value being

+ [ES5] Arguments object should inherit from Array

+
+ Make the Arguments object conform to the behaviour specified in ES5.
+ The simple portion of this is to make Arguments use Array.prototype
+ as its prototype rather than Object.prototype.
+
+ The spec then requires us to set instance.constructor to the pristine
+ Object constructor, and instance.toString and instance.toLocaleString
+ to the pristine versions from Object.prototype. To do this we now
+ make the ObjectPrototype constructor return its toString and
+ toLocaleString functions (similar to the call and apply functions
+ from FunctionPrototype).
+
+ Oddly enough this reports itself as a slight win, but given the code

+ Add a bit to TypeInfo to indicate that an object uses the standard
+ JSObject::markChildren method. This allows us to devirtualise marking
+ of most objects (though a branch is still needed). We also add a branch
+ to identify arrays thus devirtualising marking in that case as well.
+
+ In order to make the best use of this devirtualisation I've also reworked
+ the MarkStack::drain() logic to make the iteration more efficient.

+
+ The ASSERTs fired because we tested PropertySlot::slotBase() for validity,

+ This allows the implementation to be defined per architecture. Specifically this addresses the

+ pathological cases it could be slow even without calling into the
+ JavaScript virtual machine.
+ (JSC::Stringifier::willIndent): Added.
+ (JSC::Stringifier::indent): Added.
+ (JSC::Stringifier::unindent): Added.
+ (JSC::Stringifier::startNewLine): Added.
+ (JSC::Stringifier::Holder::Holder): Added.
+ (JSC::Stringifier::Holder::appendNextProperty): Added. This is the
+ function that handles the format of arrays and objects.
+ (JSC::JSONObject::getOwnPropertySlot): Moved this down to the bottom
+ of the file so the JSONObject class is not interleaved with the
+ Stringifier class.
+ (JSC::JSONObject::markStringifiers): Added. Calls mark.
+ (JSC::JSONProtoFuncStringify): Streamlined the code here. The code
+ to compute the gap string is now a separate function.
+
+ * runtime/JSONObject.h: Made everything private. Added markStringifiers.
