Revert "Activating AVX2 support by default"

Browse source 
This reverts commit ad148272b8.

Reason for revert: Causing test failures downstream.

Original change's description:
> Activating AVX2 support by default
>
> This CL activates the newly added AVX2 support by default.
> The activation is done beneath a kill-switch.
>
> Beyond the above, the CL also changes an incorrect DCHECK_GT
> to a DCHECK_GE.
