Um, Diego, when do you think that code was written?
Last week?
It hasn't been fundamentally touched in ages (I believe someone touched
the generate_vops part when we moved to having VUSE_OPS_PTR).

Dan, what is happening here is that we are only *now* discovering that
the changes made to the copy propagation of pointers were affecting
PRE.  It is not a bug in PRE, so don't get all defensive on me :)
I'm not getting defensive, i'm simply pointing out that you should have updated it when you introduced propagate_copy and may_propagate_copy.
