Fix LATERAL references to target table of UPDATE/DELETE.
I failed to think much about UPDATE/DELETE when implementing LATERAL :-(.
The implemented behavior ended up being that subqueries in the FROM or
USING clause (respectively) could access the update/delete target table as
though it were a lateral reference; which seems fine if they said LATERAL,
but certainly ought to draw an error if they didn't. Fix it so you get a
suitable error when you omit LATERAL. Per report from Emre Hasegeli.
