XLA GPU has a pass that translates synchronous collectives to asynchronous ones. All passes before this one assume that there aren't any asynchronous collectives. But, we recently added async collectives to JAX. This CL changes XLA GPU to handle input HLO programs with async collectives. This CL consists of a handful of small changes. None are particularly deep. PiperOrigin-RevId: 897309874
