Changes based on comments in https://reviews.llvm.org/D40333

Changed LoopTraversal to not be a pass, but rather a class which returns the BB order and other passes can then traverse and process the BBs.
Separated some logic to a ReachingDefAnalysis pass which is used by both BreakFalsDeps and ExecutionDomainFix.
