PowerPC - Optimization for str[n]casecmp functions

This patch provides throughput boost for the strcasecmp function
(25% on ppc32 and 40% on ppc64) and strncasecmp (15% on both ppc32
and ppc64) for POWER7. The optimization is done by manually
(strcasecmp) or automatically (strncasecmp) unrolling the test loop
to avoid CPU stalls caused by a test followed by a load.
