b6c947251b Fix to the rowvalue logic that avoids disabling rowvalue inequality 
contraints on a virtual table when the virtual table sets the omit flag.
The logic has been incorrect since row-values were added.  However, this
does not come up often as very few virtual tables implement inequality
constraints using the omit flag.  Ticket [f096d191b6641daa]
