Right now, the only stabby future is either fully stable, but allocates on each poll, or fully unsafe.

Let's make a BlessedCompilerFuture trait that uses CompilerVersion to mark the futures as stable for a given version of the compiler

Another way futures could be made faster is by storing the latest used waker next to the boxed future, and reusing it if it will_wake the new context's waker when the future is polled again. But I'm not sure how to implement that without forcing the user to write more code yet...

stabby's handling of Futures is now as fast as I think I can make it without Rust's stdlib allowing stable wakers to exist. Working on getting that through.
