[PATCH] D81301: [X86] Emit two-byte NOP when possible

This revision now requires changes to proceed.

Are two byte nops legal on all 32 bit x86?  The comment seems to imply no.

Once this question is answered and we're happy with the general design, I will ask you to split out the NFC signature change and land it separately, but let's *not* do that yet.
