1. UINTN & INTN issue for EBC architecture:

	The MAX_BIT of EBC will no longer be fixed to bit 63. It is defined as (1ULL << (sizeof (INTN) * 8 - 1)).
	Make EdkModulePkg & MdePkg EBC compiler clean: treat all EFI_STATUS error code as variable.
2. PrintLib
	Complete all missing ASSERT()s.
	Fix “\n” & “%\n” issue thanks to the clarification of MWG 0.56d.
	Adjust StatusString array to support EBC build.
3. BaseMemoryLib
	Adjust ASSERT () & function header of ComparaMem, SetMemXX, ScanMemXX to synchronize with MWG 0.56d.
4.SmbusLib
	Change Pec bit to bit 22 SmBusAddress to synchronize MWG 0.56d.
	Add ASSERT()s to check if length is illegal for SmBusBlockWrite() & SmBusProcessBlock() since it is 6 bit now.
5. PerformanceLib
	Rename “EdkDxePerformanceLib” & “EdkPeiPerformanceLib” to “DxePerformanceLib” & “PeiPerformanceLib” respectively.
	Synchronize the function header of GetPerformanceMeasurement() with MWG 0.56d.
6. BasePeCoffLoaderLib.
	Make PeCoffLoaderLoadImage () Assert() if ImageContext is NULL>
	Make PeCoffLoaderLoadImage () return RETURN_INVALID_PARAMETER if the ImageAddress in ImageContext is 0.
	Adjust some coding style.
