I don't think so. type_hash is used in two ways: individual items are
set, when we know which CU we ought to have, and a whole CU is
restored, when we know which CU we're restoring. It's always more
efficient to have a lot of small hash tables if you know precisely
which one you'll need; fewer collisions.
