LoongArch: Add ifunc support for memcmp{aligned, lsx, lasx}
According to glibc memcmp microbenchmark test results(Add generic memcmp), this implementation have performance improvement except the length is less than 3, details as below: Name Percent of time reduced memcmp-lasx 16%-74% memcmp-lsx 20%-50% memcmp-aligned 5%-20%
