> [C++] Add SSE4.2-accelerated hash kernels and use if host CPU supports

> Project: Apache Arrow
> Issue Type: New Feature
> Components: C++

> Assignee: Antoine Pitrou
> Priority: Major
> Fix For: 0.12.0
>
>
> SSE4.2 has CRC32 intrinsics that can be used to compute hash values. It seems
> it may be acceptable to use {{-msse4.2}} on isolated compilation units, but
> if this object code is used on a machine without support for the SIMD
> instructions, then it will crash
