Rebase and fix using the pointer type instead of the new indexing type. Don't introduce a new addrspacecast, since it's easily avoidable.

Since the addrspacecast is no longer inserted, I think that avoids some of the questions about pointer wrapping? The addrspacecasts are only eliminated, and ignored for computing the offset.
