If I understand correctly, then the changes in 25c8a061c5739677d2fc0af29a8cc9520207b923 mostly affected how the clang AST is created for modules. 

By adding a language runtime that supports the MS ABI, I'm trying to add the capability to downcast references to a base class when using virtual inheritance and to break when C++ exceptions are thrown.
