Daniel Berlin 7d049850f0 [MSSA] Fix PR28880 by fixing use optimizer's lower bound tracking behavior.

Summary:
In the use optimizer, we need to keep of whether the lower bound still
dominates us or else we may decide a lower bound is still valid when it
is not due to intervening pushes/pops.  Fixes PR28880 (and probably a
bunch of other things).
