commit r13-3756-g9aa1b63a5554563b7a3081391358d6cedcabea88

    Fix NULL filename handling
    
    The previous commit introduced a regression as some Ada tests end up passing
    NULL as the filename to remap_filename.  Handle this as before to fix them.
    
    gcc/
            * file-prefix-map.cc (remap_filename): Handle NULL filenames.
