cfallin created PR review comment:

In addition to adding it here, can we remove it from here and make sure we switch over any uses of that (tweaking any handwritten uses of it in-place is fine for now)? Since the opcode has unary (one src, one dst) semantics it should only appear here, not elsewhere.

I'm also slightly suspect of the two cvt* opcodes above that one in XmmRmR too, and we should see if they should be moved over too, while we're at it...
