// FIXME(mw): Anything that is produced via DepGraph::with_task() must implement
// the HashStable trait. Normally DepGraph::with_task() calls are
// hidden behind queries, but CGU creation is a special case in two
// ways: (1) it's not a query and (2) CGU are output nodes, so their
// Fingerprints are not actually needed. It remains to be clarified
// how exactly this case will be handled in the red/green system but
// for now we content ourselves with providing a no-op HashStable
// implementation for CGUs.
