Make more passes preserve dominators (or state that they preserve dominators if they all ready do). This removes two dominator recomputations prior to isel, which is a 1% improvement in total llc time for 403.gcc. The only potentially suspect thing is making GCStrategy recompute dominators if it used a custom lowering strategy. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@123064 91177308-0d34-0410-b5e6-96231b3b80d8
