Compensating 6fd763431 on postponing subtyping evar-evar problems.
Pushing pending problems had the side-effect of later solving them in
the opposite order as they arrived, resulting on different complexity
(see e.g. #4076). We now take care of pushing them in reverse order so
that they are treated in the same order.
