* Optimize not-equalities in con-/disjunctions This commit adds optimisations of not-equalities in conjunctions and disjunctions: * for conjunctions, the not-equality can be optimized away when applied together with a range or inequality, in case the not-equality point falls outside the domain of the later condition; if its on the boarder, it will modify the bound, to simply exclude the equality, if present; otherwise no optimisation can be applied; * for disjunctions, the not-equals could filter away the ranges and inequalities, unless these include an equality on the bound, in which case the entire condition becomes always true, but this would influence the score() function, so it's been omitted; * fix aggregations of inequalities in ranges This commit fixes the loop that aggregates inequalities into ranges: - it won't advance the outer loop index in case of a merge, since the current element is removed; - it will break the inner loop, since comparision against the element selected in the outer loop can't continue, as it had been removed.
