Bug #31884: Assertion + crash in subquery in the SELECT clause.
Item_in_subselect's only externally callable method is val_bool().
However the nullability in the wrapper class (Item_in_optimizer) is
established by calling the "forbidden" method val_int().
Fixed to use the correct method (val_bool() ) to establish nullability
of Item_in_subselect in Item_in_optimizer.
