    Allow optional 'family' and 'instance' keywords in associated type instances
    
    This is to allow
    
       class C a where
          type family F a
          type instance F a = Bool
    
       instance C Int where
          type instance F Int = Char
    
    Plus minor improvements relating to Trac #8506
