DESCRIPTION
A view column reference is considered equal to another column
reference if the second one is a view column and if both column
references point to the same field. For views 'same field' means
the same Item_field object in the view translation table, where
the view translation table contains all result columns of the
view. This definition ensures that view columns are resolved
in the same manner as table columns.
references resolve to the same item. It is assumed that both
items are of the same type.
RETURN
TRUE Referenced item is equal to given item
