No description provided.

Cache empty type bounds and wildcard types over empty type bounds
in separate variables. This removes some of the load on uniques hashing
and avoid creation of temporary objects.
Without function specialization we got some boxing of Addr arguments.
Use a single traversal and a todo list instead of multiple traversals
This was used only when we also handled untyped trees during pickling.
