--- Comment #4 from Sanjay Patel <spatel+llvm at rotateright.com> ---
Should be fixed with:

Note - I botched what was supposed to be an NFC add-tests-patch just before
that:

So the test diff is misleading.

Also added the missing simplification which should make it harder to get into
trouble from patterns like this:
