* genemit.c (gen_insn): Print file:lineno comment before function.

        (main): likewise.
        * gensupport.c (struct queue_elem): Add filename member.
        (queue_pattern): Initialize it; update all callers.
        (process_include): Don't free filename.
        (read_md_rtx): Set read_rtx_filename.
