MIPS: microMIPS: Optimise 'strnlen' core library function.
Optimise 'strnlen' to use microMIPS instructions and/or optimisations for binary size reduction. When the microMIPS ISA is not being used, the library function compiles to the original binary code. Signed-off-by: Steven J. Hill <Steven.Hill@imgtec.com>
