ChenTsing updated ARROW-17336:
------------------------------
Description:
In some hash algorithm , it need the round-shift, for example bits 10000000
shift left one bit should change into 00000001 and not 00000000, the highest
bit one shift to the lowest bit, if not has round-shift, we must
use 'and', 'shift', 'or' threes operations to implement,it would influn
> [C++] Implement the round-shift for fixed size data type
