r369697 changed the behavior of stripPointerCasts to no longer include aliases. However, the code in CGDeclCXX.cpp's createAtExitStub counted on the looking through aliases to properly set the calling convention of a call. The result of the change was that the calling convention mismatch of the call would be replaced with a llvm.trap, causing a runtime crash.
