Driver: Run 'clang' in C++ mode based on the name it was invoked by. We match
anything that ends with ++ or ++-FOO (e.g., c++, clang++, clang++-1.1) as being a "C++ compiler". This allows easy testing of the C++ compiler by 'ln -s clang clang++', or by 'cp clang clang++'. Based on patch by Roman Divacky. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86697 91177308-0d34-0410-b5e6-96231b3b80d8
