When an imported Objective-C property has nullability, force that nullability onto the result of its getter and the parameter of its setter, so that we have consisteny nullability among the three. SILGen assumes that this is the case, so this fixes the null_resettable-based crash in <rdar://problem/20145910>. Swift SVN r26198
