1) Revised fix for Bug 2975 - [GCCE] Illegal inline assembler in kernel/eka/drivers/debug/rmdebug/d_rmd_stepping.cpp. Should have conditionally different code for __ARMCC__ and __GCCE_ 2) Fix for Bug 2976 - [GCCE] Overlapping naked function bodies break exception-handling. 3) Fix an incidental "impossible constraint in asm" gripe.
