[Sam Parker via Phabricator via llvm-commits]

I didn't think about the extra latency of a uxt cmp, and I wouldn't have thought it useful with GISel either - so this is a pleasant surprise. Do you reckon it's worth sorting out the sign extend dag patterns before enabling? Or do you think that the change is really gonna be in the noise so much that no-one will notice?
