8f1b841e45 powerpc: Add optimized strcspn for P8 
A few minor adjustments to the P8 strspn gives us
an almost equally optimized P8 strcspn.

25dba0ad05 powerpc: Add optimized P8 strspn 
This utilizes vectors and bitmasks.  For small needle, large
haystack, the performance improvement is upto 8x.  For short
strings (0-4B), the cost of computing the bitmask dominates,
and is a tad slower.
