Summary:
Flow is broken for a bunch of people and has been for the last few days. For some reason this isn't causing any builds to fail which we will need to look into. For now, this stops the bleeding.
I *think* this is because of case sensitivity differenes between Mac and where all of our CI machines run.

Summary: Split up InitializeCore into a bunch of modules. The idea here is to make it easier for apps to just get the initialization logic they want and leave behind what they don't; for example, if you don't want the Map/Set polyfills, instead of requiring InitializeCore you can require the modules you want from it.

Summary:
This diff fixes an issue that caused the problem with `regeneratorRuntime` last Friday (more info: https://fb.facebook.com/groups/frontendsupport/permalink/2427883350560427/).
The root issue is that both `InitializeCore` and `FBInitializeCore` are included in the same bundle, this fix just prevents the bundle from being invalid once this happens..
*copied from: https://our.intern.facebook.com/intern/diff/D10444264/?transaction_id=595485237532887*
The way that `regeneratorRuntime` is polyfilled is not correct:
```
polyfillGlobal('regeneratorRuntime', () => {
// The require just sets up the global, so make sure when we first
// invoke it the global does not exist
delete global.regeneratorRuntime;
require('regenerator-runtime/runtime');
return global.regeneratorRuntime;
});
```
Since a `require`d module is only evaluated once (no matter how many times it's required), defining (and calling) a getter for `global.regeneratorRuntime` twice will end up storing `undefined` to `global.regeneratorRuntime`.
There were no issues before this diff because the ordering of requires made things work by coincidence, e.g the following code will work:
```
// Set up regenerator for the first time
polyfillGlobal('regeneratorRuntime', () => {
delete global.regeneratorRuntime;
require('regenerator-runtime/runtime');
return global.regeneratorRuntime;
});
// Set up regenerator for the second time. This will just override the previous getter (which has not even got executed so
// the `regenerator-runtime/runtime` module has not been evaluated yet.
polyfillGlobal('regeneratorRuntime', () => {
// The require just sets up the global, so make sure when we first
// invoke it the global does not exist
delete global.regeneratorRuntime;
require('regenerator-runtime/runtime');
return global.regeneratorRuntime;
});
// Now access regenerator
global.regeneratorRuntime;
```
But the following code won't work:
```
// Set up regenerator for the first time
polyfillGlobal('regeneratorRuntime', () => {
delete global.regeneratorRuntime;
require('regenerator-runtime/runtime');
return global.regeneratorRuntime;
});
// Access regenerator. This will cause the previous getter to be called, and the `regenerator-runtime/runtime` module will get evaluated.
// Here, `global.regeneratorRuntime` will have a correct value.
global.regeneratorRuntime;
// Set up regenerator for the second time. This will define a new getter for `global.regeneratorRuntime`, which will delete `delete global.regeneratorRuntime`
// and return undefined (note that `require('regenerator-runtime/runtime');` is a noop since the module has been already evaluated).
polyfillGlobal('regeneratorRuntime', () => {
// The require just sets up the global, so make sure when we first
// invoke it the global does not exist
delete global.regeneratorRuntime;
require('regenerator-runtime/runtime');
return global.regeneratorRuntime;
});
```

Summary:
There were approximately 350 unused suppressions in xplat/js when checking with .flowconfig.android
The flow team is partially responsible for this, since our release process hasn't changed since we added the flowconfig. In the diff beneath this one, I added the functionality necessary for us to not add any more unused suppressions. To test it, I made this diff. The steps were:
1. Start iOS server
2. Start android server
3. remove unused ios suppressions
4. remove unused android suppressions
5. add ios suppressions with site=react_native_ios_fb
6. add android suppressions with site=react_native_android_fb
7. remove unused ios suppressions. The ones that are unused are ones where an android comment was inserted as well, since the ios comment no longer is next to the error
8. add suppressions using ios flowconfig with site=react_native_fb
9. remove unused android suppressions. The unused ones are ones that were moved up when the cross-platform suppressions were inserted.
I'm going to make this into a script to make sure we don't contribute anymore unused suppressions from our side.

Summary:
This makes JSTimers actively register a callback for callImmediates.
Besides being generally tricky, circular dependency prevent compiling React Native code with bundlers that rely on concatenating module sources rather that evaluating code at the time of requiring, like Google Closure Compiler.
Sadly, Google Closure Compiler setup that prompted this change is complicated and brittle. And there are no good public tools to find circular dependencies among Haste-style modules (with unqualified require paths).
So some advice on a good test plan would be useful. Does Facebook have any tools to find circular dependencies with Haste-style requires?
FWIW, a check that worked for me was to replace all import paths in React Native from Haste style to normal relative paths (which I needed anyway) and then run [`madge`](https://www.npmjs.com/package/madge) on the code base:
```
$ ~/node_modules/.bin/madge --circular react-native/Libraries
Processed 390 files (7.4s) (81 warnings)
✖ Found 2 circular dependencies!
1) BatchedBridge/NativeModules.js > BatchedBridge/BatchedBridge.js > BatchedBridge/MessageQueue.js > Core/Timers/JSTimers.js
2) StyleSheet/flattenStyle.js > StyleSheet/StyleSheet.js
```
(The second cycle is already eliminated in https://github.com/facebook/react-native/commit/a8e3c7f5780516eb0297830632862484ad032c10).
[GENERAL] [MINOR] [MessageQueue] - MessageQueue implementation doesn't have a circular dependency on JSTimers.

Summary:
This PR removes the need for having the `providesModule` tags in all the modules in the repository.
It configures Flow, Jest and Metro to get the module names from the filenames (`Libraries/Animated/src/nodes/AnimatedInterpolation.js` => `AnimatedInterpolation`)
* Checked the Flow configuration by running flow on the project root (no errors):
```
yarn flow
```
* Checked the Jest configuration by running the tests with a clean cache:
```
yarn jest --clearCache && yarn test
```
* Checked the Metro configuration by starting the server with a clean cache and requesting some bundles:
```
yarn run start --reset-cache
curl 'localhost:8081/IntegrationTests/AccessibilityManagerTest.bundle?platform=android'
curl 'localhost:8081/Libraries/Alert/Alert.bundle?platform=ios'
