Backport #7841: Cyclic Module#prepend raises no exception while include does

Hello,

module P; end
module Q; include P; end
module P; include Q; end
#=> cyclic include detected

module P; end
module Q; prepend P; end
module P; prepend Q; end
#=> no error

Is this intentional?

I think it should be detected.
