If `A` has a range of `[0,0][100,INF]` and the comparison of `A < 50`. This should be optimized to `A <= 0` (which then will be optimized to just `A == 0`). This patch implement this via a new function which sees if the constant of a comparison is in the middle of 2 range pairs and change the const
