Jim Kukunas 7056741fd9 lib/raid6: Add AVX2 optimized recovery functions 
Optimize RAID6 recovery functions to take advantage of
the 256-bit YMM integer instructions introduced in AVX2.

The patch was tested and benchmarked before submission.
However hardware is not yet released so benchmark numbers
cannot be reported.
