[PATCH] D16382: Add LoopSimplifyCFG pass

A meta concern here: how do we share code between this pass and the existing SimplifyCFG pass?  It would be really unfortunate if we ended up duplicating large chunks of SimplifyCFG here.  The simple unconditional edge folding case here is fine as a starting point and the code duplication isn't too terrible, but how do we avoid problems going forward?
