There are only two really outstanding SIMD-optimized mixing functions which
were used in this competition, IMO.  The choices are the reduced-Blake2
with or without it's multiplication modification, and PWXFORM.  I suspect
between Samuel Neves, Alexander, and the Argon2 team, they could figure out
the best solution.
