Liming Gao 1c7a65eba7 UefiCpuPkg: Update SmmCpuFeatureLib pass XCODE5 tool chain
https://bugzilla.tianocore.org/show_bug.cgi?id=849

In V2, use "mov rax, strict qword 0" to replace the hard code db.

1. Use lea instruction to get the address instead of mov instruction.
2. Use the dummy address as jmp destination, and add the logic to fix up
the address to the absolute address at boot time.

Michael Kinney 09119a00cc UefiCpuPkg/SmmCpuFeaturesLibStm: Add STM library instance
Add a new instances of the SmmCpuFeaturesLib that is used by
platforms to enable the SMI Transfer Monitor(STM) feature.
This new instance is in the same directory as the default
SmmCpuFeaturesLib instance in order to share source files.

The DSC file is updated to build both SmmCpuFeatureLib
instances and to build two versions of the PiSmmCpuDxeSmm
module using each of the SmmCpuFeatureLib instances.
