Transfer function assumed a deterministic linearization, which is not the case when dividing by zero (returns [-oo,+oo]). We now use the generic linear assignment instead of the deterministic one after linearization.

Texpr assignment transfer function for polyhedra assumed a deterministic linearization, which is not the case when dividing by zero (returns [-oo,+oo]).
We now use the generic linear assignment instead of the deterministic one after linearization.
Closes #76.
