- Introduce new struct AsyncGeneratorRequest, which holds information pertinent to resuming execution of an AsyncGenerator, such as the Promise associated with the async generator request. It is intended to be used as a singly linked list, and holds a pointer to the next item in te queue. - Introduce JSAsyncGeneratorObject (subclass of JSGeneratorObject), which includes several new internal fields (`queue` which contains a singly linked list of AsyncGeneratorRequest objects, and `await_input` which contains the sent value from an Await expression (This is necessary to prevent function.sent (used by yield*) from having the sent value observably overwritten during execution). - Modify SuspendGenerator to accept a set of Flags, which indicate whether the suspend is for a Yield or Await, and whether it takes place on an async generator or ES6 generator. - Introduce interpreter intrinsics and TF intrinsic lowering for accessing the await input of an async generator - Modify the JSGeneratorStore operator to understand whether or not it's suspending for a normal yield, or an AsyncGenerator Await. This ensures appropriate registers are stored. - Add versions of ResumeGeneratorTrampoline which store the input value in a different field depending on wether it's an AsyncGenerator Await resume, or an ordinary resume. Also modifies whether debug code will assert that the generator object is a JSGeneratorObject or a JSAsyncGeneratorObject depending on the resume type.
