[vm] Runtime type check in await 'await e' should check that e is a Future<flatten(S)>, where S is a static type of e before awaiting e. If e is not a Future<flatten(S)>, then 'await e' should await Future.value(e) instead of e. So futures of incompatible type are not awaited and soundness is not violated. TEST=tests/language/async/await_type_check_test.dart (Based on https://dart-review.git.corp.google.com/c/sdk/+/267422.)

 the suspended function later.
 
+### AwaitWithTypeCheck stub
+
+AwaitWithTypeCheck is a variant of Await stub which additionally passes type argument `T`
+and calls `_SuspendState._awaitWithTypeCheck` in order to test if the value has a
+correct `Future<T>` type before awaiting.
+
+This runtime check is needed to maintain soundness in case value is a Future of an
+incompatible type, for example:
+
+```
+final FutureOr<Object> f = Future<Object?>.value(null);
+Object x = await f; // x == f, not null.
+```
+
 ### ReturnAsync stub
 
 ReturnAsync stub = Return stub which calls `_SuspendState._returnAsync`.
