Reorder some tree codes

I'm sympathetic to the idea that it would be cooler to improve the
middle end so that it did this optimization itself, but I don't know
how hard that would be. Does anyone have an idea about that? (The
documentation issue remains in this case, in that someone might
reorder the codes, and then we have a performance degradation, if it's
no longer possible to collapse the checks into a range check.)
I think it will now *if* the codes are all tested in order.
