cmd/compile: update PGO profile

Since the default.pgo profile is collected, there has been a lot
of development and refactoring in the compiler. It's time to
refresh the compiler's PGO profile. As we are in the freeze, there
will probably not be many major changes to the compiler, so this
should be good for Go 1.22.

Profile collected by running the cmd/compile/profile.sh script on
the linux-amd64-perf gomote.

This also shows that a stale profile (the old one) still brings a
speedup, but smaller, as expected.

As before, the profile is transferrable. Benchmark results on
