Update `rustc` PGO benchmark list

I noticed that the `rustc` PGO crates do not contain any crate that would stress the trait system. I tried adding and removing various crates to the PGO benchmark list here. Here's what I found:

- Removing [`externs` and `match-stress`](https://perf.rust-lang.org/compare.html?start=c0672870491e84362f76ddecd50fa229f9b06dff&end=b056963e0324fa76c721d79f12658a64cfa4cb5e&stat=instructions:u) regresses these two benchmarks by up to 15 % and removing them doesn't improve anything else, so we should keep them.
- Adding [`keccak`](https://perf.rust-lang.org/compare.html?start=52cc7795245347500ddf6dc959cf58a7abe2d935&end=6fd27b23fd7860c79752479173b4a1b877cba490) regresses `diesel`, otherwise it doesn't do much.
- Adding [`tt-muncher`](https://perf.rust-lang.org/compare.html?start=c0672870491e84362f76ddecd50fa229f9b06dff&end=2ab5994d9cdfb098344895f7d8d5aee3cf3d6eff&stat=instructions:u) improves it very slightly, not worth it to include it IMO.
- Adding just [`diesel`](https://perf.rust-lang.org/compare.html?start=00755e4ca68f12ed200e921276788ab19975e85f&end=cd37706ad459ee8ddfda4631be71120cb7eda19d) improves it by up to 1.5 % and others crate slightly, but regresses `bitmaps`.
- Adding [`bitmaps`](https://perf.rust-lang.org/compare.html?start=67a9bcb31b85e87cc8bb327022632e48a0ca64a8&end=0cd80ba74425e6614cd52c4ea2bf6b0191c6dbc4&stat=instructions:u) improves both it and diesel, no other regressions.
- Adding [both](https://perf.rust-lang.org/compare.html?start=77972d2d0134fb597249b3b64dcf9510a790c34e&end=f968d7af511d750db96cfdc04f844fb017c079ce) `bitmaps` and `diesel` produces quite nice improvements and almost no regressions.
- Adding [ucd](https://perf.rust-lang.org/compare.html?start=b5caa5a8421f84cb7664f999b7635801bcf3f96a&end=327cc09917311f65cf427e6c0bf5f7424af9fd05&stat=instructions:u) did not have a large effect on primary benchmarks.
