PR14759: Debug info support for C++ member pointers. This works fine with GDB for member variable pointers, but GDB's support for member function pointers seems to be quite unrelated to DW_TAG_ptr_to_member_type. (see GDB bug 14998 for details) llvm-svn: 171698

Now that llvm-dwarfdump supports flags to specify which DWARF section to dump, use them in tests that run llvm-dwarfdump. This is in order to make tests as specific as possible. llvm-svn: 173498
