    ApiAnnotations : parens around a context with wildcard loses annotations
    
    Summary:
    In the following code, the extra set of parens around the context end up
    with detached annotations.
    
        {-# LANGUAGE PartialTypeSignatures #-}
        module ParensAroundContext where
    
        f :: ((Eq a, _)) => a -> a -> Bool
        f x y = x == y
    
    Trac ticket #10354
    
    It turns out it was the TupleTy that was the culprit.
    
    This may also solve #10315
    
    Test Plan: ./validate
