target/arm: Drop copies in gen_sve_{ldr,str}
Since we now get TEMP_TB temporaries by default, we no longer need to make copies across these loops. These were the only uses of new_tmp_a64_local(), so remove that as well. Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
