After a bit more revision, mostly updating outdated comments and
naming adjustments, I've pushed this.
Per the benchmark results I showed in [1], due to the performance of
having the AllocSet free list pointers stored at the end of the
allocated chunk being quite a bit slower than having them at the start
of the chunk, I adjusted the patch to have them at the start.
Time for me to go and watch the buildfarm results come in.
