[PATCH] D22034: [MSVC][DLL] use local vftable mangling only exported classes with virtual destructor

David, do you know real programs that relay on constexpr and dllexport semantic that doesn't work on MSVC? If not, I think we might want to report error message instead of miss-compile it as MSVC does. Anyway current implementation is not compatible with MSVC in much more common case without constexp. At the moment my patch works with your example just because it only changes mangling but don't use imported vftable that seems to be wrong. Is it you changes somewhere that prevent using imported vftable?
