Sei Lisa e123866e6e Apply DeMorgan in some cases that were not caught. ...

Example: the optimization of if(i < 2 || i) was suboptimal, because FoldTree was done before FoldCond. In a first stage, the || was removed: if(!!(i < 2 | i)); when folded, the inner ! was optimized first and the result was if(!(1 < i & (!i))), which FoldCond wasn't smart enough to handle.

The new optimization takes over from there, and converts if(!(!a & b)) with b boolean, in any order, to if(a | !b). When applied to the above expression, it gets folded to if(i < 2 | i) as expected, which is optimal.

Also, new function: IsAndBool (see docstring), used on b in the above example.
