Overall result: ❌✅ regressions and improvements - ACTION NEEDED

Benchmarking this pull request likely means that it is perf-sensitive, so we're automatically marking it as not fit for rolling up. While you can manually mark this PR as fit for rollup, we strongly recommend not doing so since this PR may lead to changes in compiler perf.

Next Steps: If you can justify the regressions found in this try perf run, please indicate this with @rustbot label: +perf-regression-triaged along with sufficient written justification. If you cannot justify the regressions please fix the regressions and do another perf run. If the next run shows neutral or positive results, the label will be automatically removed.

Looks like removing libcore from the profile set doesn't hurt much. Now I'll try to also completely remove rustc-perf gathering when gathering LLVM PGO profiles.

Looks like after the initial stage 2 build with an instrumented LLVM, there is already 6 GiB of profiles (after benchmarks it's usually 20 GiB). So instrumenting stage 2 build provides a lot of data! I'll try what happens if we delete the profiles.
