For other logical operators adding `NOT` in front of the expression results in negation of the binary operator, e.g.: `NOT a > b` becomes `a <= b` but this is not the case for `NOT a = b`. This implements the negation of equals when encountered in the SELECT clause or needs to be translated to a painless script (e.g.: `HAVING NOT count(*) = 10`) Previously, an `SqlIllegalArgumentException[Not supported yet]` was thrown. Fixes: elastic#34558
