In the case you are getting problems with this particular loop, I would
be very interested how unit-at-a-time relate to it.
Now when I was forced to know more than I ever wanted about it I think I
can reorganize it to the worklist if still needed and avoid the
quadratic bootleneck.
This unit-at-a-time patch partly does that - instead of wallking the
dependency graph at varconst time, it does it inside middle end with
worklists already, but still varconsts does TREE_USED checks that may
iterate when templates gets instantiated.
