// Subtle: note that we are not invoking
// `infcx.at(...).dropck_outlives(...)` here, but rather the
// underlying `dropck_outlives` query. This same underlying
// query is also used by the
// `infcx.at(...).dropck_outlives(...)` fn. Avoiding the
// wrapper means we don't need an infcx in this code, which is
// good because the interface doesn't give us one (so that we
// know we are not registering any subregion relations or
// other things).
// FIXME convert to the type expected by the `dropck_outlives`
// query. This should eventually be fixed by changing the
// *underlying query*.
