Reland "call skcms_OptimizeForSpeed()"

Browse Source 
This is a reland of 3b8feb331a

Original change's description:
> call skcms_OptimizeForSpeed()
> 
> I've guarded src and dst separately, so that we can land,
> rebaseline just the src change, and then later (when it
> does something), rebaseline optimizing dst separately.
> 
> Small threshold tweak to keep a unit test passing.
