(make_range): Don't merge unsigned case with range containing upper bound;

instead merge just with zero and convert a range with no upper bound to
opposite one with no lower bound.
(merge_ranges): In (+,-) case, don't treat subset specially if the upper
bounds are the same; fix typo in others case here.
