Nikolai Saoukh 010f55d3fb UefiCpuPkg: error: invalid instruction mnemonic 'retf' 
.S assembler files must be AT&T syntax ones. So Intel syntax mnemonic is not good. Discovered by clang integrated assembler.

Anderw Fish 07da1ac8c4 UefiCpuPkg: CpuExceptionHandlerLib: Make self modifying code work with Xcode 
CpuExceptionHandlerLib has code that contains absolute relocations, not supported by
Xcode for X64, and it then copies this code to an alternate location in memory. It is 
very hard to write IP relative self-modifiying code. I had to update AsmVectorNumFixup()
to also patch in the absolute addressess after the code was copied.
