Internal coding: Assert that user#() don't overlap.
...
Any use of a user() must now be declared, generally in the Visitor class with
AstUser#InUse arbitrary_object
This lets the code track if there's another request for the same user(),
preventing nasty hard to debug cases where they overlap. This will also
call user#ClearTree(), so a bunch of those were removed, though many
extranious ones still remain.
