> CRC32 returns the cyclic redundancy check value of a given string as a 32-bit
> unsigned value, null if string is null. In mysql and hive the syntax like
> select CRC32('test') = 3632233996
> Though it is not a hash function, however the pattern and behavior looks
> similar with hash functions (md5, sha1, sha2 etc..), so I put codegen in
> HashCalcCallGen
