One thing that first pops out to me is that we can do the refactor of
hash_initial_lookup() as an independent piece, without the extra paths
introduced. But rather than returning the bucket hash and have the
bucket number as an in/out argument of hash_initial_lookup(), there is
an argument for reversing them: hash_search_with_hash_value() does not
care about the bucket number.

Likely so, though that does not hurt to show the intention to the
reader.

So I would like to suggest the attached patch for this first piece.
What do you think?

It may also be an idea to use `git format-patch` when generating a
series of patches. That makes for easier reviews.
