        Bug fixes from trunk

        PR fortran/30034
        * resolve.c (resolve_formal_arglist): Exclude the test for
        pointers and procedures for subroutine arguments as well as
        functions.

        PR fortran/30237
        * intrinsic.c (remove_nullargs): Do not pass up arguments with
        a label. If the actual has a label and the formal has a type
        then emit an error.

        PR fortran/25135
        * module.c (load_generic_interfaces): If the symbol is present
        and is not generic it is ambiguous.

        PR fortran/23060
        * intrinsic.c (compare_actual_formal ): Distinguish argument
        list functions from keywords.
        * intrinsic.c (sort_actual): If formal is NULL, the presence of
        an argument list function actual is an error.
        * trans-expr.c (conv_arglist_function) : New function to
        implement argument list functions %VAL, %REF and %LOC.
        (gfc_conv_function_call): Call it.
        * resolve.c (resolve_actual_arglist): Add arg ptype and check
        argument list functions.
        (resolve_function, resolve_call): Set value of ptype before
        calls to resolve_actual_arglist.
        * primary.c (match_arg_list_function): New function.
        (gfc_match_actual_arglist): Call it before trying for a
        keyword argument.

        PR fortran/27900
        * resolve.c (resolve_actual_arglist): If all else fails and a
        procedure actual argument has no type, see if a specific
        intrinsic matches.

        PR fortran/24325
        * resolve.c (resolve_function): If the function reference is
        FL_VARIABLE this is an error.
