Summary: We introduce a strict policy for C++ CTU. It can work across TUs only if the C++ dialects are the same. We neither allow C vs C++ CTU. We do this because the same constructs might be represented with different properties in the corresponding AST nodes or even the nodes might be completely different (a struct will be RecordDecl in C, but it will be a CXXRectordDecl in C++, thus it may cause certain assertions during cast operations).
