leonardchan added a comment. OK so I instead wrote a script that generated the tests for me since changing each individual case by hand was painful. All the `-cc1` tests now match, although I don't know any ways of simplifying the IR further to help reduce test size. I would definitely love to know if there are any ways to simplify the instructions. Unfortunately for `convergent.cl`, the codegen still differs slightly around the end of the loop when using `-instcombine` in addition to `instnamer`:

Unfortunately there doesn't seem to be a new PM equivalent for `instnamer` (but one does exist for `instcombine`). For simplicity, should we stick with using the legacy driver for now?
