This is a temporary step until we allow Promises everywhere.
Currently this serializes to a Lazy which can then be consumed in this same
slot by the client.
We're adding an option to Fizz to support an alternate output format
that doesn't rely on inline script tags (see #25437). The two outputs
will share the same "instruction set" of functions. These functions are
currently inlined into the source file; to make this a bit more maintainable,
and eventually have a single source of truth, in preparation for the new option,
this commit moves the instruction set to a separate files that are imported.
In the future, we could improve this further by running Closure on the
instruction set and generating it at build time. This isn't an urgent
improvement, though, because we rarely modify the instruction set.

* Missing Hooks
* Remove www forks. These can use __SECRET... instead.
* Move cache to separate dispatcher
These will be available in more contexts than just render.
Publish an aliasable entry for `react-dom` top level package exports for use in server environments. This is a stub containing only the exports that we expect to retain in the top level once 19 is released
In #24967, I changed the behavior of Offscreen so that passive effects
are not fired when the tree is hidden. I accidentally applied this
behavior to the old LegacyHidden API, too, which is a deprecated
internal-only type that www has been using while they wait for Offscreen
to be ready.
This fixes LegacyHidden so that the effects do not get deferred, like
before. The new behavior still remains in the Offscreen API, which is
experimental and not currently in use in www.
* track resources in different roots separately
* flow types
* add test demonstrating portals deep into shadowRoots
* revert hostcontext changes
* lints
* funge style cache key a la ReactDOMComponentTree
* hide hacks in componentTree
* Update safe-string-coercion to handle additions of string literals
Adding strings shouldn't trigger a lint violation of this rule, since
adding strings are always safe.
The existential type `*` was deprecated and a codemod provided to replace it. Ran that and did some manual fixups:
```sh
node_modules/.bin/flow codemod replace-existentials --write .
```

Usage of the new `use` hook needs to conform to the rules of hooks, with
the one exception that it can be called conditionally.

- method unbinding is no longer supported in Flow for soundness, this added a bunch of suppressions
- Flow now prevents objects to be supertypes of interfaces/classes

This upgrade made more expressions invalidate refinements. In some
places this lead to a large number of suppressions that I automatically
suppressed and should be followed up on when the code is touched.
I think most of them might require either manual annotations or moving
a value into a const to allow refinement.

This was a large upgrade that removed "classic mode" and made "types first" the only option.
Most of the needed changes have been done in previous PRs, this just fixes up the last few instances.

This contains one code change, renaming the local function `ChildReconciler` to `createChildReconciler` as it's called as a function, not a constructor and to free up the name for the return value.
