Jakub Kuderski 874f12d8e5 [Dominators][CodeGen] Fix MachineDominatorTree preservation in PHIElimination 
Summary:
PHIElimination modifies CFG and marks MachineDominatorTree as preserved. Therefore, it the CFG changes it should also update the MDT, when available. This patch teaches PHIElimination to recalculate MDT when necessary.

This fixes the `tailmerging_in_mbp.ll` test failure discovered after switching to generic DomTree verification algorithm in MachineDominators in D67976.
