RFR(XXS): 8235510 : java.util.zip.CRC32 performance drop after 8200067

[Viswanathan, Sandhya]

The changes introduced in 8200067 cause performance to drop for java.util.zip.CRC32 on Intel platforms supporting vector pclmulqdq.
An enhanced algorithm is needed which takes into account latency and throughput of vector pclmulqdq. For now, we need to backout the changes.
