isl_map_coalesce: avoid dropping constraints redundant wrt implicit equalities
isl_map_coalesce first detects implicit equalities in the basic maps.
If two basic maps can indeed be coalesced, then fuse() would

Other constraints that imply that this constraint is actually an equality
are redundant with respect to the equality and would not get copied

In principle, we could just modify fuse() to add the implicit equalities
