[PATCH 3/4] Move hash_entry and eq_entry into cooked_index::do_finalize

[Tom Tromey <tromey@adacore.com>]

I was briefly confused by the hash_entry and eq_entry functions in the
cooked index.  They are only needed in a single method, and that
method already has a couple of local lambdas for a different hash
table.  So, it seemed cleaner to move these there as well.
