isl_map_coalesce: handle more cases

In particular, if one basic map has a single constraint that cuts
off all or part of the other basic map such that the part that is cut
off lies entirely on a hyperplane adjacent to the constraint,
then try to combine the two basic maps by adding some wrapping constraints.
