aarch64: Optimized implementation of memcmp
The loop body is expanded from a 16-byte comparison to a 64-byte comparison, and the usage of ldp is replaced by the Post-index mode to the Base plus offset mode. Hence, compare can faster 18% around > 128 bytes in all. Checked on aarch64-linux-gnu. Reviewed-by: Wilco Dijkstra <Wilco.Dijkstra@arm.com>
