[John Fastabend via Phabricator via llvm-commits]

jrfastab added a comment.

@yonghong-song I can merge the fix with this patch, but why do we eliminate MOV_rr? I'm trying to see where/why this case would happen I'm not seeing other backends with similar logic. Could we just remove the entire block for all cases?
