Thank you so much for catching this. This was just a dumb oversight on my part. I originally had something along these lines and changed it because `getUniqueVRegDef()` won't assert on physical registers. However, I unfortunately changed it after I ran my usual bootstrap tests with lit and test-suite and just prior to posting.
