These slowdowns are because we are now using PCG instead of the
Mitchell/Reeds LFSR for the benchmarks. PCG is in fact a bit slower
(but generates statically far better random numbers).

On the other hand, compared to the original "update benchmarks" CL,
the cleanups we've made more than compensate for PCG being a bit
slower than LFSR, at least on 64-bit x86. ARM64 (Apple M1) is a bit
slower: perhaps the 64x64→128 multiply is slower there for some reason.
386 is noticeably slower, but it's also a non-SSA backend.
