We already prohibited this in most cases (in r130710), but had some bugs in our enforcement of this rule. Specifically, this prevents the following combinations: * -x c -std=clN.M, which would previously effectively act as if -x cl were used, despite the input being a C source file. (-x cl -std=cNN continues to be disallowed.) * -x c++ -std=cuda, which would previously select C++98 + CUDA, despite that not being a C++ standard. (-x cuda -std=c++NN is still permitted, and selects CUDA with the given C++ standard as its base language. -x cuda -std=cuda is still supported with the meaning of CUDA + C++98.) * -x renderscript -std=c++NN, which would previously form a hybrid "C++ with RenderScript extensions" language. We could support such a thing, but shouldn't do so by accident. llvm-svn: 301497
