pointer-to-member type, produce a null value of the right type. This fixes a bug where throwing an exception of type nullptr_t and catching it as a pointer-to-member would not guarantee to produce a null value in the catch handler. The fix is pretty simple: we statically allocate a constant null pointer-to-data-member representation and a constant null pointer-to-member-function representation, and produce the address of the relevant value as the adjusted pointer for the exception. llvm-svn: 276016
