target/loongarch: Drop temp_new
Translators are no longer required to free tcg temporaries, therefore there's no need to record temps for later freeing. Replace the few uses with tcg_temp_new. Reviewed-by: Song Gao <gaosong@loongson.cn> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
