1) Fix GCC version EBC interpreter bug.

Browse Source 
Add missing EFIPAI for EbcInterpret and ExecuteEbcImageEntryPoint().
	Get return value in EbcLLCALLEXNative(), remove EbcLLGetReturnValue().

2) Fix IA32 EBC interpreter bug on MOVsnw and MOVsnd.

3) Some cleanup
	Add missing ReturnEBCStack() for IA32 build.
	Remove unnecessary EbcLLGetStackPointer() for X64 and IPF build.
	Remove deadcode EbcLLGetStackPointer() and EbcLLGetReturnValue() in IA32/X64/IPF ASM code.
	Dump more info in CommonEbcExceptionHandler().
