With reinterpret_cast, we can get completely unrelated types in a region hierarchy together; this was resulting in CXXBaseObjectRegions being layered directly on an (untyped) SymbolicRegion, whose symbol was from a completely different type hierarchy. This was what was causing the internal buildbot to fail. Reverts r161911, which merely masked the problem. llvm-svn: 161960
