tree-pretty-print.c (dump_array_domain): Split out from dump_generic_node; fix off-by-one error on zero-based array bounds.

        * tree-pretty-print.c (dump_array_domain): Split out from
        dump_generic_node; fix off-by-one error on zero-based array bounds.
        (dump_generic_node): Use it.
        (print_declaration): Likewise.
