Nit: it's probably worth adding a test case ensuring that the pass actually merges the functions with constant ptrauth expressions when it's possible. W/o such a test, a dummy implementation which just unconditionally disables merging of functions with such expressions would still pass the tests, which is probably not a desired thing.

Feel free to ignore.
