aarch64: Optimized implementation of memrchr
Considering the excellent performance of memchr.S on glibc 2.30, the same algorithm is used to find chrin. Compared to memrchr.c, this method with memrchr.S achieves an average performance improvement of 58% based on benchtest and its extension cases. Checked on aarch64-linux-gnu.
