Fix regression in behavior of clang -x c++-header -fmodule-name=XXX
-fsyntax-only. The driver accidentally stopped passing the input filenames on to -cc1 in this mode due to confusion over what action was being requested. This change also fixes a couple of crashes I encountered when passing multiple files to such a -cc1 invocation. llvm-svn: 345803
