I see a lot of our hash tables get initially sized to 37 entries.
This is going to cause quite a bit of re-hashing as we expand the hash.
I think for quite a few of these we should measure their sizes
across a set of "reasonable" sized compilations, and start with
that. The average size of the hashes while bootstraping would
seem to be a reasonable first cut.
