[Tests] Add tests to highlight sibling loop optimization order issue for exit rewriting

The issue addressed in r363180 is more broadly relevant.  For the moment, we don't actually get any of these cases because we a) restrict SCEV formation due to SCEExpander needing to preserve LCSSA, and b) don't iterate between loops.
