Well, a human wrote "tmp = tree2" -- sometimes one likes to count down
instead of up, I guess.
We can make Coccinelle order the parameters alphabetically, but I don't
know how to do so without duplicating most of the semantic patch. And
thats would result in e.g. SWAP(new_tree, old_tree), which might be odd
as well.
I'd just leave them in whatever order they were, but that's probably
because I'm lazy.
