I rebased my branch off of master and rebuilt it, and also rebuilt the baseline from master. Both versions were configured with --with-lto and --enable-optimizations. The benchmark numbers are rather different this time[1]. pidigits is slower, but nbody is still inexplicably faster. Should I run the benchmark without a PGO build (i.e without --enable-optimizations)?

Also, I've attached the output from the pyperformance run to the aforementioned gist.
