MdePkg: Replace Opcode with the corresponding instructions.
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3790
Replace Opcode with the corresponding instructions.
The code changes have been verified with CompareBuild.py tool, which
can be used to compare the results of two different EDK II builds to
determine if they generate the same binaries.
