The ranges are the ssa_name range itself. There will be some minor
issues to deal with when dealing with ssa_name overlap, but its nothing
we can't sort out when -g is specified, and will therefore not cost
computation time when -g isnt specified. So it wont change the
generated code, it just might mean a little more conflict resolution to
separate out when each of the multiple ssa_names attached actually
expire. It will just require a little processing and thought.
And its WAY better than what we have now.
