Split the runtime function for initializing a promise into AwaitPromisesInit and AwaitPromisesInitOld, the former not firing the INIT hook and being used by the AwaitOptimized builtin. In addition to this the AsyncHooks now caches all the previously inited promises and checks that the init hook is not fired twice for the same promise. Modified test expectations for the new async ids in the async hooks tests.
