Summary: Release note: Adds experimental React functional component folding optimizations This PR is stacked upon PRs #1118 and #1117. Thus, those PRs should be merged before this PR is merged to reduce noise in the diff. This PR adds a new React Reconciler into Prepack's serialization process, so that React components trees can be folded/inlined into a single component at build time. To fold a component tree, it must be explicitly done via `__registerReactComponentRoot(nameOfComponent)`. This PR only attempts to fold React functional components, not React ES2015 class components (that will come in another PR at a later date). Furthermore, the `props` parameter on a root component must contain Flow type annotations (otherwise we will have no idea what the values might be). Support flow `propTypes` might also be an addition, but not for this PR. If the reconciler comes across a component that it cannot fold/inline, it will "bail-out" and try and continue the process without that particular component being folded into the tree. An example of how this all works (input): ```jsx function App(props: {title: string}) { return ( <div> <ChildComponent title={props.title} /> </div> ); } function ChildComponent(props) { return ( <span> <SubChildComponent {...props} /> </span> ); } function SubChildComponent(props) { return <span>{props.title.toString()}</span> } __registerReactComponentRoot(App); global.App = App; ``` Output: ```jsx (function () { "use strict"; var _$1 = this; var _0 = function (props) { var _$0 = props.title; return <div><span><span>{_$0}</span></span></div>; }; _$1.App = _0; }).call(this); ``` Closes https://github.com/facebook/prepack/pull/1120 Differential Revision: D6237333 Pulled By: trueadm fbshipit-source-id: b58c7d8979ca79a766bb2ee2eb01a380d37c3101
