Subject: [PATCH] [LoongArch][Clang] Make the parameters and return value of
 {x,}vorn.v builtins `unsigned char` vectors

All other bitwise vector builtins use `unsigned char` vector operands,
so it does not make too much sense to use `signed char` for the orn
operation alone.

The same change has been also proposed for GCC:
