This PR contains a few major improvements: * Code duplication has been removed. * Everything has been refactored so that the implementation is much easier to understand. * `future_to_promise` is now implemented with `spawn_local` rather than the other way around (this means `spawn_local` is faster since it doesn't need to create an unneeded `Promise`). * Both the single threaded and multi threaded executors have been rewritten from scratch: * They only create 1-2 allocations in Rust per Task, and all of the allocations happen when the Task is created. * The singlethreaded executor creates 1 Promise per tick, rather than 1 Promise per tick per Task. * Both executors do *not* create `Closure`s during polling, instead all needed `Closure`s are created ahead of time. * Both executors now have correct behavior with regard to spurious wakeups and waking up during the call to `poll`. * Both executors cache the `Waker` so it doesn't need to be recreated all the time. I believe both executors are now optimal in terms of both Rust and JS performance.
