* Improve code for the empty frozenset singleton: - Handle both frozenset() and frozenset([]). - Do not use singleton for frozenset subclasses. - Finalize the singleton. - Add test cases. * Factor-out set_update_internal() from set_update(). Simplifies the code for several internal callers. * Factor constant expressions out of loop in set_merge_internal(). * Minor comment touch-ups.
