Log message:
    Rewrite hashbulkdelete() to make it amenable to new bucket locking
    scheme.  A pleasant side effect is that it is *much* faster when deleting
    a large fraction of the indexed tuples, because of elimination of
    redundant hash_step activity induced by hash_adjscans.  Various other
    continuing code cleanup.
