    Add GHC.Prim.oneShot
    
    to allow the programer to explictitly set the oneShot flag. This helps
    with #7994 and will be used in left folds. Also see
    https://ghc.haskell.org/trac/ghc/wiki/OneShot
    
    This commit touches libraries/base/GHC/Event/Manager.hs (which used to
    have a local definition of the name oneShot) to avoid a shadowing error.
