    API Annotations: AnnTilde missing
    
    In T10689a.hs, the fragment
    
        data instance Sing (z :: [a])
          = z ~ '[] =>
            SNil
          | forall (m :: a)
                   (n :: [a]). z ~ (:) m n =>
            SCons (Sing m) (Sing n)
    
    ends up with the AnnTilde annotations for the two tildes not attached to
    the final AST.
    
    This patch moves the AnnTilde to the right place.
    
    Closes #11321
