EnumSimplification was designed to avoid generating a hashmap from BB to RPO, which is well-intentioned, but I think it's simpler and safer just to use an RPO map here. This patch changes the code to: - Simplify the code for reading/debugging. - Skip the sorting step. - Allow removing this land mine: C++ copy ctors need to really copy. - Skip the searching step in each loop iteration. - Be as space efficient. No redundant BB pointers in an array (and removed the AA pointer). Swift SVN r21102
