…types This patch is a temporary alternative to llvm#130768 If we detect a situation where a forward declaration is C++ and the definition DIE is Objective-C, then just don't try to complete the type (it would crash otherwise). In the long term we might want to add support for completing such types rdar://145959981

…types This upstreams swiftlang#10313. If we detect a situation where a forward declaration is C++ and the definition DIE is Objective-C, then just don't try to complete the type (it would crash otherwise). In the long term we might want to add support for completing such types. We've seen real world crashes when debugging WebKit and wxWidgets because of this. Both projects forward declare ObjC++ decls in the way shown in the test. rdar://145959981
