Merge CRC+memcpy functionality into Extend function.

This improves performance through improved instruction level parallelism.  We mostly do the copying separately, but in lockstep with the crc streams. We don't reuse the loads between the crc calculation and the copy, since the loads are to different register types, except for VPCLMUL streams.
