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.
