Hi Adhemerval and Jianbo,

I've customized string-fzi.h and string-maskoff.h for LoongArch (see
attachment).  With them on top of Adhermerval's v5 "Improve generic
string routines" patch and GCC & Binutils trunk, the benchmark result
seems comparable with the assembly version for strchr, strcmp, and
strchrnul.

By the way I've tried to unroll the loop in strchr manually, but then
the compiler produced some bad thing (moving words from a register to
another with no reason) and the result is slower.

I've not really plotted the the result, just took a quick look with my
eyes.  You can try the bench with my headers in sysdeps/loongarch.
