Use hw accelerated implementation of crc32 when possible
Xtrabackup is using CRC32 as part of xbstream and xbcrypt formats, it benefit from hardware optimized crc32 greatly.
There are two widely used CRC32 polynomials - ISO3309 (used in zlib, gzip, deflate, etc) and CRC32-C. xbtream and xbcrypt formats are using first one. Intel's PCLMUL instruction can be used to implement it.
