// Call our implementations of memcpy/move/set/clr rather than the ARM supplied
// ones.
// 
// Note that the AEABI switched the order of arg2 and arg3 to save an intruction
// when calling 'memset' from 'memclr'.
//
// Prototypes are:
//   void __aeabi_memset8(TAny* aTrg, unsigned int aLength, TInt aValue);
//   void __aeabi_memset4(TAny* aTrg, unsigned int aLength, TInt aValue);
//   void __aeabi_memset(TAny* aTrg, unsigned int aLength, TInt aValue);
