phases: invalidate the phases set less often on retract boundary

We already have the information to update the phase set, so we do so directly
instead of invalidating the cache.

This show a sizeable speedup in our `perf::unbundle` benchmark on the
many-draft mozilla-try repository.

Case-changing renames should work:

  $ hg mv a A
  $ hg mv A a
  $ hg st

addremove after case-changing rename has no effect (issue4590)

  $ hg mv a A
  $ hg addremove
  recording removal of a as rename to A (100% similar)
  $ hg revert --all
  forgetting A
  undeleting a

test changing case of path components

  $ mkdir D

We assume anyone running the tests on a case-insensitive volume on OS
X will be using HFS+. If that's not true, this test will fail.
