I also ran the reliable performance benchmark suite with LTO+PGO. There is no significant performance change on these benchmarks:

The largest change is on scimark_lu (-13%), but there was an hiccup on the previous change which is probably a small unstability in the benchmark. It's not a speedup of these changes.

The second largest change is on spectral_norm: +9%. But this benchmark is known to be unstable, there was already a small peak previously. Again, I don't think that it's related to the changes.
