When instrumenting C++ code, ubsan ends up referencing the ubsan_type_hash_* object files, which require linking against the C++ ABI library. When building with "clang -x c++", the code is handled as C++, but the compiler still only links as if it was C. Change all cases of "%clang -x c++" into "%clangxx -x c++". This fixes a lot of ubsan tests in mingw mode. Differential Revision: https://reviews.llvm.org/D147687
