Chris Lattner d0a96ba38a Add a simple but useful optimization for identifier lookup. Each time we
query the hash table, when we look up an identifier that isn't at the head
of it's bucket's list, move it there.  This reduces the number of list
traversals in the common case where identifiers are used in bursts.
