AVX2: Avoid expensive AVX-SSE transitions
Refer to
https://software.intel.com/sites/default/files/m/d/4/1/d/8/11MC12_Avoiding_2BAVX-SSE_2BTransition_2BPenalties_2Brh_2Bfinal.pdf
for more information. This eliminates all AVX-SSE transitions detected
with the Intel SDE tool.

easier to follow the flow of data through the algorithms.
