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:
> *CRC32 Zlib polynomial 0x04C11DB7*
> |KeyValueType-IO|Before(MB/s)|After(MB/s)|Improvement|
> |TextType-Write|425.98|602.92|+42%|
> |TextType-Read|796.06|1716.59|+116%|
> |BytesType-Write|474.25|686.84|+45%|
> |BytesType-Read|844.96|1955.03|+131%|
> |UnknownType-Write|434.84|608.81|+40%|
> |UnknownType-Read|805.76|1733.82|+115%|

>
> *CRC32C Castagnoli polynomial 0x1EDC6F41*
>
> |KeyValueType-IO|Before(MB/s)|After(MB/s)|Improvement|
> |TextType-Write|423.39|606.55|+43%|
