Other than the inline comment, I think this patch is fine but I'll let Hal have a look for the official stamp of approval.

This will just check that you don't have an LXSIWZX after the move. I think you don't want this instruction emitted in this test case at all. So it's probably better to use `--implicit-check-not` in the FileCheck invocation.
