lib/raid6: Add AVX512 optimized gen_syndrome functions
Optimize RAID6 gen_syndrom functions to take advantage of
the 512-bit ZMM integer instructions introduced in AVX512.
AVX512 optimized gen_syndrom functions, which is simply based
on avx2.c written by Yuanhan Liu and sse2.c written by hpa.
The patch was tested and benchmarked before submission on
a hardware that has AVX512 flags to support such instructions
