[PATCH v99,13/13] MIPS: microMIPS: Optimise 'strnlen' core library function.

["Steven J. Hill" <sjhill@mips.com>]

From: "Steven J. Hill" <sjhill@mips.com>

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.
