Fixed LP bug #806057.
A table expression with a natural join or a USING clause is transformed
into an equivalent expression with equi-join ON conditions. If a reference
to a virtual column happened to occur only in these generated equi-join
conditions then it was not erroneously marked in the TABLE::vcol_set bitmap.
This could lead to wrong results for queries containing natural join
expressions or USING clauses.
