Parse JOIN/ON conditions with the proper visibility of input columns,
ie, consider only the columns coming from the JOIN clause's sub-clauses.
Also detect attempts to reference columns belonging to other tables
(which would still be possible using an explicitly-qualified name).
I'm not sure this implements the spec's semantics 100% accurately, but
at least it gives plausible behavior.
