    Original change's description:
    > [async-iteration] implement spec-change to `yield` in async generators
    > 
    > Per https://github.com/tc39/proposal-async-iteration/pull/102/files:
    > 
    > AsyncGeneratorResolve no longer unwraps a value component. Instead, the
    > value is unwrapped before the builtin call via Await, allowing Promise
    > rejections to affect the generator control flow.
    > 
    > Thus, all `yield <expr>` implicitly become `yield await <expr>`.
    > 
    > Additionally, `return <expr>` becomes `return await <expr>`. Finally, when
    > the generator is resumed with `.return()`, the parameter passed to .return()
    > is awaited before generator execution properly continues).
