I'm honestly not sure how to do that. I may have missed a method, but if you
have the base pointer how do you use that to compute the rest of the
expression? For instance, if `p->p->p` is the base, how do I use that to emit
the full expression `p->p->p->a.b.c.d.e[index]`?
I can skip the extra load here by using the pointer from the `ArrayLV` GEP.
