Summary: Require DominatorTree when requiring/preserving LoopInfo in the old pass manager BreakCriticalEdges tries to keep LoopInfo and DominatorTree updated if they exist. However, since commit r321653 and r321805, to update LoopInfo we must have a DominatorTree, or we will hit an assert. To fix this we now make a couple of passes that only required/preserved LoopInfo also require DominatorTree. This solves PR37334.
