  [MC] Use a variant to hold MCCFIInstruction state (NFC) (#164720)

AMDGPU requires more complex CFI rules, normally these would be
expressed with .cfi_escape, however this would make the CFI unreadable
and makes it difficult to update registers in CFI instructions (also
something AMDGPU requires).
