Summary: Earlier iterations of mutable buffer memory planning relied on the insert copy_ pass to inject the placeholder node as the output. That is pretty hacky and doesn't compose well with the reinplacing pass. Fortunately we already have this pass so we can manually set the lifespan here to be infinite.
