Summary:
- Enables async/await in .babelrc and transformer.js
- Adds regenerator to package.json. Users still need to explicitly require the regenerator runtime -- this is so that you only pay for what you use.
- Update AsyncStorage examples in UIExplorer to use async/await
- Update promise tests in UIExplorer to use async/await in addition to the promise API

Fixes#773, #1055
The resolver was getting a bit unwieldy because a lot has changed since the initial writing (porting node-haste).
This also splits up a large complex file into the following:
* Makes use of classes: Module, AssetModule, Package, and AssetModule_DEPRECATED (`image!` modules)
* DependencyGraph is lazy for everything that isn't haste modules and packages (need to read ahead of time)
* Lazy makes it fast, easier to reason about, and easier to add new loaders
* Has a centralized filesystem wrapper: fast-fs (ffs)
* ffs is async and lazy for any read operation and sync for directory/file lookup which makes it fast
* we can easily drop in different adapters for ffs to be able to build up the tree: watchman, git ls-files, etc
* use es6 for classes and easier to read promise-based code
Follow up diffs will include:
* Using new types (Module, AssetModule etc) in the rest of the codebase (currently we convert to plain object which is a bit of a hack)
* using watchman to build up the fs
* some caching at the object creation level (we are recreating Modules and Packages many times, we can cache them)
* A plugin system for loaders (e.g. @tadeuzagallo wants to add a native module loader)
Test Plan:
* ./runJestTests.sh react-packager
* ./runJestTests.sh PackagerIntegration
* Export open source and run the e2e test
* reset cache
* ./fbrnios.sh run and click around

Add PerformanceLogger to keep track of JS download, initial script execution and
full TTI.
Test Plan:
The Native side currently calls `addTimespans` when it's finish initializing
with the six values (start and end for the three events), so I just checked it
with a `PerformanceLogger.logTimespans()` at the end of the function.

Previously, our XMLHttpRequest implementation would only update the readyState when the download was fully completed. This diff adds support for receiving incremental data updates as the download happens, which can be monitored by adding the onreadystatechange event handler.
As a performance optimization, incremental data updates are only sent if the onreadystatechanged handler has been set in the JS, otherwise it just sends the whole data block once download is complete, as before.
Test Plan:
* Run the UIExplorer XMLHttpRequest example (in both OSS and Catalyst) to see incremental downloads working.
* Run the Movies app to see regular (non-incremental) downloads in action
* Run any network-based app in Catalyst shell to verify RKDataManager still works

ErrorUtils.reportError is intended for reporting handled errors to the
server, like timeouts, which means that we shouldn't shove them in the
developer's face.
Test Plan: add `require('ErrorUtils').reportError(new Error('error'))` and see a useful error message with stack but no redbox. Debugger confirms `reportSoftException` is called but it doesn't do anything yet. `reportFatalError` and throwing exceptions still show redboxes.

document shimming must run before anything else. However, we don't currently guarantee that. This moves the document shimming into `document.js` which is used as a polyfill.
Test Plan:
* start server
* go to playground app
* require `NativeModules` as the first thing
* open chrome debugger
* no error

Test Plan: I arc patched and ran movies demo and storyline, they work fine
Summary:
Requiring ExceptionsManager in renderApplication (added in D2023119) led to a transitive require of ExecutionEnvironment, which has to run after InitializeJavaScriptAppEngine.
InitializeJavaScriptAppEngine is the right place for this sort of logic because we control the order that things are loaded, so move the console.error hook initialization there.

Test Plan: Loaded shell app in simulator with Chrome debugging with no errors.
