[Bug tree-optimization/42436] New: VRP should mark non-trapping integer divisions

[rguenth at gcc dot gnu dot org]

In PR42108 a division is found to be non-trapping by VRP but neither PRE nor
LIM can make use of that information (well, because VRP doesn't mark the
divisions in any meaningful way).
