Thanks~
* Modify the patch according the Yetus's suggestion.
* Run the native tests on arm64 , the execute file is
:hadoop-rel-release-3.1.1/hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-nativetask/target/native/test/nttest,
attaching the results file:
[^aarch64_nativetask_test.log]
* The issue is optimized for performance, adding new tests in
test_bulk_crc32.c if need it.
* Testing the hadoop test case (include: terasort/wordcount/kmeans..) with
the test tool HiBench-HiBench-7.0 , all testcases had passed.

> Add support for aarch64 CRC instructions in nativetask module, optimize the
> CRC32 and CRC32C.
> Use the benchmark tools : nttest , the improvement is quite substantial:
