optabs-query: Use opt_machine_mode for smallest_int_mode_for_size [PR115495].
In get_best_extraction_insn we use smallest_int_mode_for_size with
struct_bits as size argument. PR115495 has struct_bits = 256 and we
don't have a mode for that. This patch makes smallest_mode_for_size
and smallest_int_mode_for_size return opt modes so we can just skip
over the loop when there is no mode.
