This patch ports the PlaceSafepoints pass to the new pass manager as it is used by .NET/Mono. Compatibility with the legacy pass manager is maintained by adding PlaceSafepointsLegacyPass. This pass also depends on PlaceBackedgeSafepointsLegacyPass, which has been kept in the legacy-only variant, since it is apparently used only from PlaceSafepointsPass. It has been renamed, though, to indicate its legacy interface. Reviewed By: aeubanks Differential Revision: https://reviews.llvm.org/D136163
