[PATCH 0/4] XCODE5 toolchain binary patching fix

["Lendacky, Thomas" <thomas.lendacky@amd.com>]

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=2340

Commit 2db0ccc2d7fe ("UefiCpuPkg: Update CpuExceptionHandlerLib pass
XCODE5 tool chain") introduced binary patching in the
ExceptionHandlerAsm.nasm in order to support the XCODE5 toolchain.
However, the CpuExceptionHandlerLib can be used during SEC phase which
would result in binary patching of flash.

This series creates a new CpuExceptionHandlerLib file to support
the required binary patching for the XCODE5 toolchain, while reverting
the changes from commit 2db0ccc2d7fe in the standard file.

This is accomplished in phases:
  - Create a new XCODE5 specific version of the ExceptionHandlerAsm.nasm
    file
  - Update the DSC files that use the CpuExceptionHandlerLib library to
    to use the XCODE5 version of the library when the XCODE5 toolchain
    is used.
  - Revert the changes made by commit 2db0ccc2d7fe in the standard file.

I don't have access to an XCODE5 toolchain setup, so I have not tested
this with XCODE5. I would like to request that someone who does please
test this.
