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

[Alexandre Ganea via Phabricator via llvm-commits]

aganea added a comment.

A ReactOS developer pointed out that the default for x86 cl.exe is `/arch:SSE2` which generates `66 90` when specifying `/hotpatch`. However with `/arch:[IA32|SSE] /hotpatch` the previous sequence `8B FF` is emitted instead. I will replicate the behavior.
