PR13529: Don't crash if the driver sees an unused input file when running as 'clang-cpp'. For now, the test uses "REQUIRES: shell" to determine if the host system supports "ln -s", which it uses to create a 'clang-cpp' symlink. This is a bit hacky and should likely be directly supported by lit.cfg. llvm-svn: 161317

// PR13529: Don't crash.
Turn Driver::CCCIsCXX and CCCIsCPP into a single Mode enum, and add a new option --driver-mode= to control it explicitly. The CCCIsCXX and CCCIsCPP flags were non-overlapping, i.e. there are currently really three modes that Clang can run in: gcc, g++ or cpp, so it makes sense to represent them as an enum. Having a command line flag to control it helps testing. llvm-svn: 186605
