  1. lib/x86/crc32: add VPCLMULQDQ implementations of CRC-32 

    This improves CRC-32 performance on some of the latest x86 CPUs.  Three
implementations are added: VPCLMULQDQ/AVX2 and VPCLMULQDQ/AVX512VL which
use 256-bit vectors, and VPCLMULQDQ/AVX512F/AVX512VL which uses 512-bit
vectors.  To reduce downclocking effects, the implementation with
512-bit vectors isn't used on Intel CPUs 10th generation and older.
