- Given that null-pointer optimization is target specific, i.e. only a
valid optimization for targets which terminally trap upon a null-pointer
dereference (which doesn't seem like a particularly useful behavior in
itself, as opposed to some other non-disruptive/non-terminal behavior);
many of the VRP test cases involving pointers should not correspondingly
presume the presence of this optimization by default?
