component.destroyed

[Rich-Harris]

Just ran into a case where it would be useful to know, within a component method, whether or not the component still exists (the method runs in a setTimeout, which could fire after the component has been destroyed).

With knowledge of the internals there are various ways to do this, and you could also do it by setting a custom property inside a destroy event handler, but it might be nice if there was a standard, documented way to do it:

export default {
  methods: {
    thingThatRunsPeriodically() {
      if (this.destroyed) return;
      doSomeStuff();
    }
  }
};

Descartes would say - "I am destroyed, therefore I am not"

@Rich-Harris this was never merged into master, is that an oversight?

Would help in eliminating some console warnings in svelte-hot-loader
