Updated the patch with `update_test_checks.py` run with the changes applied on top of https://reviews.llvm.org/rGfd9026131e6c5de6f4e582d5c85c5b5588672dfb
Looks like what I'd expect. It's optimizing it through the opaque use call, but that doesn't look like a problem to me.

I also removed the `setHasNoSignedWrap(false)` and it did not change the test results or the upodate_test_checks changes. Not sure what I was seeing yesterday.
