// The algorithm for updating NRVO candidate is as follows:
//   1. All previous candidates become invalid because a new NRVO candidate is
//      obtained. Therefore, we need to clear return slots for other
//      variables defined before the current return statement in the current
//      scope and in outer scopes.
//   2. Store the new candidate if its return slot is available. Otherwise,
//      there is no NRVO candidate so far.
