    Move DFunUnfolding generation to TcInstDcls
    
    The desugarer had a fragile case to generate the Unfolding for a
    DFun. This patch moves the unfolding generation to TcInstDcls, where
    all the pieces are to hand.
    
    Fixes Trac #11742
    
    (cherry picked from commit db9e4eb4e3fe916df7a69da1b211083ad6068aff)
