At least at first, it may make more sense to keep the red-black trees as-is, and
to look up what appear to be symbol-tagged pointers twice, once as-is (to find
any kind of object) and once offset by '(char *) lispsym - Lisp_Symbol' (to find
only symbols). Although a bit slower, this won't require any changes to the
rbtree code so it's cleaner. We can then time the optimization you have in mind,
to see whether it's worth doing.
