/**
* @assertion We say that a type T0 is a subtype of a type T1 (written T0 <: T1)
* when:
* Right Object: if T1 is Object then:
* - if T0 is an unpromoted type variable with bound B then T0 <: T1 iff
* B <: Object
* - if T0 is a promoted type variable X & S then T0 <: T1 iff S <: Object
* - if T0 is FutureOr<S> for some S, then T0 <: T1 iff S <: Object.
* - if T0 is S* for any S, then T0 <: T1 iff S <: T1
* - if T0 is Null, dynamic, void, or S? for any S, then the subtyping does not
* hold (per above, the result of the subtyping query is false).
* - Otherwise T0 <: T1 is true.
* @description Check that if T0 is a promoted type variable X & S and
* S <: Object then T0 is subtype of Object even is X is not subtype of Object
