commit e46b76816c67ca8651aaf2c119632ff1bdb3766f

    Make Data.{Bifoldable,Bitraversable} -XSafe
    
    Test Plan:
    Previously, `Data.{Bifoldable,Bitraversable}` were being inferred as
    `Unsafe` due to a transitive `Data.Coerce` import from `Data.Functor.Utils`.
    This rectifies this unfortunate mistake.
