[edk2-devel] [PATCH v2 5/6] MdePkg: Remove the macro definitions regarding Opcode.

[Jason Lou]

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3790

Remove the macro definitions regarding Opcode because new version of
NASM tool(e.g. v2.15.05) supports the corresponding instructions.
Note: This patch need to be merged after other NASM code change to avoid
compilation errors.
