commit 37310efa53e5c341d2b525c4f3a62696fb64caab

    Fix printing of an `IfacePatSyn`
    
    Now the existentially quantified type variables are printed
    at the correct location when printing a pattern synonym type
    from an `IfacePatSyn`. The function `pprIfaceContextMaybe`
    has been removed as it is no longer needed.
    
    Fixes #11524.
