I confirmed earlier that removing the new code from builtins_id fixes this issue, which I suspect means that PGO is deciding to make different optimizations and produce different output.

Other functions in the same stack also do not show their arguments, so I think the best thing to do here is fix the test to not care about arguments being in the display. The result of gcc's PGO on debug symbols should not affect how we make Python work.

I'll update the regex in the test tomorrow.
