Armv8 CRC32 optimization (#772)
ARMv8 (AArch64) CPUs implement the CRC32 extension which is implemented by inline assembly ,
so they can also benefit from hardware acceleration in IO-intensive workloads.
The patch optimizes crc32c calculate with the armv8 crypto instruction(Intrinsics) when available
rather than original linear crc instructions.
