Xuelei Zhang 0237b61526 aarch64: Optimized implementation of strcpy
Optimize the strcpy implementation by using vector loads and operations
in main loop.Compared to aarch64/strcpy.S, it reduces latency of cases
in bench-strlen by 5%~18% when the length of src is greater than 64
bytes, with gains throughout the benchmark.

Checked on aarch64-linux-gnu.
