        * c-common.c (check_function_restrict): New function.
        (check_function_arguments): Add FNDECL argument.  Call
        check_function_restrict if -Wrestrict.
        * c-warn.c (warn_for_restrict): Remove ARGS argument, add ARGARRAY
        and NARGS.  Use auto_vec for ARG_POSITIONS, simplify.
        * c-common.h (check_function_arguments): Add FNDECL argument.
        (warn_for_restrict): Remove ARGS argument, add ARGARRAY and NARGS.

        handle -Wrestrict here.

        check_function_arguments caller.
