* Initial React DevTools support for Fiber
* Record a newly failing irrelevant test
This is fine because we don't use it in Stack anyway (at least not that part), and we also rely on Set/Map in other parts of code.
The newly failing test is the one saying "it works without Map/Set".
* Explicitly check for Fiber DevTools support
This lets us ignore pre-Fiber DevTools instead of crashing them by injecting a different API.
* Track the roots in DevTools instead
* Lol Dan this is not how warnings work in our codebase
* Move injection to the renderer
* Notify DevTools about unmounts
* Make it work in production
* Fix lint and flow
* Fixups
* Address feedback
When visiting the yields, the root is the stateNode of the coroutine. If
its return value is wrong we'll end up at the alternate of the
workInProgress which will start scanning its children which is wrong.
There are a few different issues:
* Updates result in unnecessary duplicate placements because it can't find the current fiber for continuations.
* When run together, coroutine update and unmounting tests appear to lock down in an infinite loop. They don't freeze in isolation.
I don't have a solution for this but just leaving it for future fixes.
Coroutines was kind of broken because it tried to do reparenting and
enabling state preservation to be passed along the coroutine. However,
since we couldn't determine which Fiber was "current" on a reified yield
this was kind of broken.
This removes the "continuation" part of yields so they're basically just
return values. It is still possible to do continuations by just passing
simple functions or classes as part of the return value but they're not
stateful.
This means that we won't have reparenting, but I actually don't think we
need it. There's another way to structure this by doing all the state in
the first phase and then yielding a stateless representation of the result.
This stateless representation of the tree can then be rendered in different
(or even multiple) locations.
Because we no longer have a stateful continuation, you may have noticed
that this really no longer represent the "coroutine" concept. I will
rename it in a follow up commit.
It is slightly more useful this way because when we want to find host nodes
we typically want to do so in the second phase. That's the real tree where
as the first phase is more of a virtual part of the tree.
