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.
