Gather LLVM PGO profiles from `rustc-perf` suite on real-world crates

This PR expands the benchmark suite used to gather LLVM PGO profiles in CI from `libcore` to several real-world crates. I hand-picked a few crates, but the list is up for debate.

Previous results that we got from running `syn,cargo,serde` looked pretty [good](https://perf.rust-lang.org/compare.html?start=2631aeef823a9e16d31f999d3f07001e5fcc4b3d&end=abf097afa10dde1aa3d8a1d422724a46aab79bf3).

Running `libcore` + `rustc-perf` with some number of crates is repeated now (and for BOLT it will also be needed), so maybe we can extract it to a bash function?
