arch/86: AVX RAID5 xor checksumming
From: Jim Kukunas

Hi Folks,
The following patch adds an AVX implementation of the RAID5 xor checksumming
functions.
Based on xor_speed, the AVX implementation appears to be ~32% faster than the
SSE implementation on my i7 2600:
generic_sse: 15088.000 MB/sec
avx: 19936.000 MB/sec
Thanks.
