RFR(M): 8217459: [PPC64] Cleanup non-vector version of CRC32

PPC64 currently contains static tables for CRC32/CRC32C calculations. We only need some of them depending on Endianess and on whether vector instructions are available or not.
We can get rid of quite some code when we generate these constants at startup as we already do for the vector version.

In addition, we can save one register in the vector case because we can use one constants pointer for all related constants.


Please review.

Best regards,
