Update bundle sizes for 16.5.1 release

* Enhance dev warnings for forwardRef render function

- For 0 parameters: Do not warn because it may be due to usage of the
  arguments object.

- For 1 parameter: Warn about missing the 'ref' parameter.

- For 2 parameters: This is the ideal. Do not warn.

- For more than 2 parameters: Warn about undefined parameters.

* Make test cases for forwardRef warnings more realistic

* Add period to warning sentence

+
+* Use [Online Playgrounds](https://reactjs.org/docs/getting-started.html#online-playgrounds) to get a taste of React.
+* [Add React to a Website](https://reactjs.org/docs/add-react-to-a-website.html) as a `<script>` tag in one minute.
+* [Create a New React App](https://reactjs.org/docs/create-a-new-react-app.html) if you're looking for a powerful JavaScript toolchain.
+
+You can use React as a `<script>` tag from a [CDN](https://reactjs.org/docs/cdn-links.html), or as a `react` package on [npm](https://www.npmjs.com/).

-## Installation
-
-React is available as the `react` package on [npm](https://www.npmjs.com/). It is also available on a [CDN](https://reactjs.org/docs/cdn-links.html).

+# IO "suspense" demo
+
+## What is this fixture?
+
+This is a demo application based on [Dan Abramov's](https://github.com/gaearon) recent [JSConf Iceland talk](https://reactjs.org/blog/2018/03/01/sneak-peek-beyond-react-16.html) about React.
+
+It depends on a local build of React and enables us to easily test async and "suspense" APIs in a more "real world app" like context.
+
+## Can I use this code in production?
+
+No. The APIs being tested here are unstable and some of them have still not been released to NPM. For now, this fixture is only a test harness.
+
+## How do I run this fixture?
+
+Clone the React repository.
+
+First, open this file locally:
+
+* `packages/shared/ReactFeatureFlags.js` (make sure you didn't open a similarly named file!)
+
+Set [the `enableSuspense` flag](https://github.com/facebook/react/blob/d79238f1eeb6634ba7a3df23c3b2709b56cbb8b2/packages/shared/ReactFeatureFlags.js#L19) to `true` and save the file.
+
+**After you've done that,** follow these steps:
+
+```shell

+# CPU async rendering demo
+
+## What is this fixture?
+
+This is a demo application based on [Dan Abramov's](https://github.com/gaearon) recent [JSConf Iceland talk](https://reactjs.org/blog/2018/03/01/sneak-peek-beyond-react-16.html) about React.
+
+It depends on a local build of React and enables us to easily test async "time slicing" APIs in a more "real world app" like context.
+
+## Can I use this code in production?
+
+No. The APIs being tested here are unstable and some of them have still not been released to NPM. For now, this fixture is only a test harness.
+
+There are also known bugs and inefficiencies in master so **don't use this fixture for demonstration purposes either yet**. Until they are fixed, this fixture is **not** indicative of React async rendering performance.
+
+## How do I run this fixture?
+
+```shell
+# 1: Build react from source
+cd /path/to/react
+yarn
+yarn build dom-client,core,simple-cache-provider,schedule --type=NODE
+
+# 2: Install fixture dependencies
+cd fixtures/unstable-async/time-slicing/
+yarn
+
+# 3: Run the app
+yarn start
+```
