> * currently simplification decomposes the AND operands
> * simplifies all operands
> * runs main simplification
> * (re) simplifies all operands which are negated
> Idea is to make the recursion as a first step; which could also push negation
> further down; and skip the simplification at end completely - as its not
> connected to a structural change.
