  1. ARROW-3849 Leverage Armv8 crc32 extension instructions to accelerate … 

    …the hash computation for Arm64

The Hash utility leverages SSE4 to accelerate the Crc32 data hash computation for x86.
Correspondingly, we will leverage the Arm crc32 extension instructions
to accelerate the hash computation for AArch64.
