rebase: improve base revset performance

The old revset had pretty terrible performance on large repositories (12+
seconds). This new revset achieves the same result in only 0.7s. As we improve
the underlying revset APIs we can probably get this revset down to 'only(base,
dest)::', but at the moment that version still takes 2s.
