SSE4 implementation

Also not as impactful, but definitely measurable is an SSE4 variant.  This will
actually run on Atoms and a much larger number of other pre-Haswell CPUs.  

The ZFS On Linux version does 8 padds per loop iteration because they are
avoiding the pmovzxdq instruction.  This is probably to be compatible with
SSSE3 and not require SSE4.
