performance: speedup computation of unstable revisions

In their current state, revset calls can be very costly, as we test
predicates on the entire repository.

This change drops revset call in favor of direct testing of the
phase of changesets.

Performance test on my Mercurial checkout
- 19857 total changesets,
- 1584 obsolete changesets,
- 13310 obsolescence markers.

Before:
