Add new heuristic for resolving instruction sizes.
Add new heuristic for resolving instruction sizes. This applies to the the
decision between extended and base page addressing by calculating the range
of possible addresses (if reasonably knowable) and deciding on whether to
force extended addressing based on that. (If the whole range is outside the
direct page, extended addressing is required.)
