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.
