[PATCH] D140273: [MC] Use `MCRegister` instead of `unsigned` in `MCTargetAsmParser`

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added a comment.

Can you also fix ARC/AVR/M68k/LoongArch in this patch? `-DLLVM_ERIMENTAL_TARGETS_TO_BUILD='ARC;AVR;LoongArch;M68k'`



================
Comment at: llvm/lib/Target/X86/AsmParser/X86AsmParser.cpp:4941
   int64_t Off;
   if (parseSEHRegisterNumber(X86::VR128XRegClassID, Reg))
     return true;
----------------
Update the `RegNo` parameter of `parseSEHRegisterNumber`
