Suppress unused warnings for selectors for some derived classes
Although derived `Read`, `Show`, and `Generic` instances technically
don't //use// the record selectors of the data type for which an
instance is being derived, the derived code is affected by the
//presence// of record selectors. As a result, we should suppress
`-Wunused-binds` for those record selectors when deriving these classes.
This is accomplished by threading through more information from
`hasStockDeriving`.
