We're out of tree codes; now what?

The tuples conversion is only going to make things worse in the short term.

Doug, isn't there a lang_tree bit you can make available, and use it
to make the tree code field 9 bits wide?  I know this is also not
quite optimal, but adding 24 bits like this is an invitation to
everyone to start using those bits, and before you know it we're stuck
with a larger-than-necessary tree structure... :-(  (plus, it's not 32
bits but 64 bits extra on 64 bits hosts...)
