Add support for per-location warning groups.

        * c-common.c (c_wrap_maybe_const): Remove TREE_NO_WARNING.
        (c_common_truthvalue_conversion): Replace direct uses of
        TREE_NO_WARNING with warning_suppressed_p, suppress_warning, and
        copy_no_warning.
        (check_function_arguments_recurse): Same.
        * c-gimplify.c (c_gimplify_expr): Same.
        * c-warn.c (overflow_warning): Same.
        (warn_logical_operator): Same.
        (warn_if_unused_value): Same.

OK once prereqs are approved.
