Add support of ARM64 hardware crc instructions for nativetask

CRC instructions are introduced since ARM64V8 ISA. With this extension Arm supports CRC32(0x04C11DB7) and CRC32C(0x1EDC6F41) checksum hardware computation.
This patch enables support on such arm64 platform, similiar as HADOOP-11660.
Benchmark is done on a A57 platform using nttest (hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-nativetask/target/native/test/nttest), and the result is as following:
Before (sw crc):
[ RUN ] Perf.CRC
17/10/10 03:05:18 INFO CRC time: 0.10112s size: 100.000M speed: 988.92M/s
17/10/10 03:05:18 INFO CRC32C time: 0.10043s size: 100.000M speed: 995.74M/s
[ OK ] Perf.CRC (216 ms)

After (hw crc):
[ RUN ] Perf.CRC
17/10/11 05:06:27 INFO CRC time: 0.03173s size: 100.000M speed: 3151.14M/s
17/10/11 05:06:27 INFO CRC32C time: 0.03146s size: 100.000M speed: 3178.97M/s
[ OK ] Perf.CRC (77 ms)
