Another thing that I'll probably add to v8: Prefetching. This is
probably necessary just so I can have parity with the existing
heapam.c function that the new code is based on,
heap_compute_xid_horizon_for_tuples(). That will probably help here,
too.

I don't quite see this part. Do you mean top_block_groups_favorable() here?
