  Update documentation on x86 constraint codes (#68830)

This updates the documentation on these inline asm constraint codes to
match reality. Context:
https://github.com/llvm/llvm-project/issues/68818#issuecomment-1758180020

Note: dropping also the `'o'` from the docs because I can't find any
mention of it in X86ISelLowering.cpp.
