Teach instsimplify that X+Y>=X+Z is the same as Y>=Z if neither side overflows,
plus some variations of this. According to my auto-simplifier this occurs a lot
but usually in combination with max/min idioms. Because max/min aren't handled
yet this unfortunately doesn't have much effect in the testsuite.
