performance: speedup computation of unserved revisions
In their current state, revset calls can be very costly, as we test
predicates on the entire repository. The "unserved" filter is used
in multiple applications, and in particular in some branch cache
loading operations. We need to make it fast.
This change drops revset calls in favor of direct testing of the
phase of a changeset.
