Nikolaj Bjorner 52c6f7c3b1 refine the safety check for leaving basis. As long as all base variables are unbounded in compatible directions as the non-basic variable we can detect unbounded variables. This partial check fixes integer divergence in a case exposed by Karpenov. Establishing or converting this to a check that always identifies unbounded integer variables is left for further analysis.
