  -----------
  [X86] Remove incomplete support for 'Y' has an inline assembly constraint by itself.

Y is the start of several 2 letter constraints, but we also had
partial support to recognize it by itself. But it doesn't look
like it can get through clang as a single letter so the backend
support for this was effectively dead.
