commit 9b9d2ee305625543503ff2b5cc7696609cec0fa5

    Add a final demand analyzer run right before TidyCore
    
    in order to have precise used-once information in the exported
    strictness signatures, as well as precise used-once information on
    thunks. This avoids the bad effects of #11731.
