performance: speedup computation of mutable revisions
In their current state, revset calls can be very costly, as we test
predicates on the entire repository. The "mutable" filter is used
during branch cache loading operation. We need to make it fast.
This change drops revset calls in favor of direct testing of the
phase of a changeset.
Performance test on my Mercurial checkout
- 19857 total changesets,
- 1646 mutable revision
Before:
