  Log Message:
  -----------
  [X86] Make the if statement structure for inline assembly constraints 'l', 'r', 'q', 'Q', and 'R' the same.

These did similar things but had slight differences. For example
'Q' didn't allow f64, but the others did.

    M llvm/test/CodeGen/X86/asm-reject-reg-type-mismatch.ll

  Log Message:
  -----------
  [X86] Don't allow f80 to be used with the 'q', 'r', 'l', 'Q' or 'q' inline assembly constraints.

It was previously trying to use the 64-bit class, but 80 isn't
evenly divisible by 64 so it will trigger a crash.
