LoongArch: Add ifunc support for strrchr{aligned, lsx, lasx}
According to glibc strrchr microbenchmark test results, this implementation could reduce the runtime time as following: Name Percent of rutime reduced strrchr-lasx 10%-50% strrchr-lsx 0%-50% strrchr-aligned 5%-50% Generic strrchr is implemented by function strlen + memrchr, the lasx version will compare with generic strrchr implemented by strlen-lasx + memrchr-lasx, the lsx version will compare with generic strrchr implemented by strlen-lsx + memrchr-lsx, the aligned version will compare with generic strrchr implemented by strlen-aligned + memrchr-generic.
