Simon Tatham 98ea4b30c2 [ARM,MVE] Make the MVE intrinsics work in C++! ... Summary: Apparently nobody has tried this in months of development. It turns out that `FunctionDecl::getBuiltinID` will never consider a function to be a builtin if it is in C++ and not extern "C". So none of the function declarations in <arm_mve.h> are recognized as builtins when clang is compiling in C++ mode: it just emits calls to them as ordinary functions, which then turn out not to exist at link time. The trivial fix is to wrap most of arm_mve.h in an extern "C". Added a test in clang/test/CodeGen/arm-mve-intrinsics which checks basic functioning of the MVE header file in C++ mode. I've filled it with copies of existing test functions from other files in that directory, including a few moderately tricky cases of overloading (in particular one that relies on the strict-polymorphism attribute added in D72518). (I considered making //every// test in that directory compile in both C and C++ mode and check the code generation was identical. But I think that would increase testing time by more than the value it adds, and also update_cc_test_checks gets confused when the output function name varies between RUN lines.)
