[PATCH] D30128: [LazyMachineBFI] Reimplement with getAnalysisIfAvailable

What's the compile time savings you're seeing from not computing these analyses unnecessarily?

Side rant: I think some of the names in LLVM are really poorly chosen, `DominatorTree` in fact is not an analysis but the result of an analysis.
