The former.  Of course if you want to spend the time rewriting the
GIMPLE parts of address-space support even better (shouldn't be
too hard given nobody really cares about it too much).

I just think that by modeling an API that looks like we have "fixed"
the GIMPLE parts makes it easier for somebody to do that.
