Summary:
The only callsite of `coalesce` looks like this:
```
newEvent.coalesce(oldEvent);
```
The default `coalesce` implementation returns the event with the most recent timestamp. When the events have the same timestamp then, using the variable names from above, `coalesce` returns `oldEvent`.
This change updates `coalesce`'s implementation to make it explicit that it returns `this` (`newEvent` in the variable names from above) in the case of a tie.
The motivation for this change is related to scroll events. In my team's app, we were seeing scroll events being emitted with the same timestamp and the coalescing logic was causing the oldest scroll event to be chosen. This was causing our JavaScript code to receive stale scroll information and the way the JavaScript code utilized this stale scroll information resulted in the ScrollView settling on the wrong scroll position.
**Test plan (required)**
Verified that scroll events work properly in a ScrollView in a test app. Also, my team's app uses this

Follow on in https://github.com/facebook/react-native/pull/10864.
**Motivation**
ncuillery Is has a lot of experience with upgrading RN projects (see his [talk](http://www.slideshare.net/ncuillery/introducing-the-new-reactnative-upgrade)) and is rewriting 'react-native upgrade' to use git.
He tells me that we actually want git to merge changes in the .pbxproj file. In his words: "Making the project.pbxproj invisible for "git diff" means that react-native-git-upgrade will never be able to upgrade the project.pbxproj."
Note the git docs explicitly recommend not to use git to merge .pbxproj files: https://git-scm.com/book/en/v2/Customizing-Git-Git-Attributes#Binary-Files
ncuillery do we have an alternative? Some ideas:
1. Use a 3rd-party tool in 'react-native upgrade' to merge the .pbxproj file?
2. We could always re-generate and overwrite the .pbxproj file (never merge) and then run 'react-native link' to update native 3rd-party dependencies in the Xcode project?
3. Last resort: stay away

Summary:
As said in #10944, there's not yet some good infos on how to profile the javascript.
I'm adding a mention to two ways of doing it (`react-addons-perf` and chrome profiler), feel free to correct me on this.
I almost added an example for `react-addons-perf` but I'm not sure what's the correct way to use. Here's the way I use it:
```javascript
import Perf from 'react-addons-perf';
....
componentDidMount() {
console.log('start perf tracking');
Perf.start();
setTimeout(() => {
console.log('stop perf tracking');
Perf.stop();
Perf.printExclusive();
}, 10000);
}
...

Summary:
TextInput rounds padding down with `floor` when measuring. However, it rounds padding up with `ceil` when rendering.
This change makes things consistent by moving TextInput's rendering code to use `floor` as well. It looks like this is the intended behavior because commit bdff10b moved measuring from `ceil` to `floor`. It looks like TextInput's rendering code was just overlooked in that commit.
**Test plan (required)**
Verified TextInput padding works in a test app. Also, my team uses this change in our app.

Summary:
When running in strict mode we run into the following error:
“Cannot assign to read only property 'product' of object '#<WorkerNavigator>’”
Moreover navigator.product = ‘ReactNative’; didn’t actually change the product value. Without strict mode this was silently ignored.
By using our defineProperty function we are able to run in strict mode and now navigator.product is really ReactNative.
See https://github.com/facebook/react-native/issues/10881 for more information
---------------
Long story short - if we run in strict mode, the current code throws an error :
`Cannot assign to read only property 'product' of object '#<WorkerNavigator>' initializeCore.js`
(the current version of initializeCore.js doesn't have 'use strict'; on top, but if you are unfortunate enough to have a babel module that ads this for you, you are guaranteed to run into this. Moreover our contributing guidelines say that we should have 'use strict'; https://github.com/facebook/react-native/blob/master/CONTRIB

- Published to Sinopia locally ([docs](https://github.com/facebook/react-native/tree/master/react-native-cli))
- Ran 'react-native init MyApp', the correct files were created (no more .npmignore, but have .gitignore):
$ cd MyApp
$ ls -a
. .flowconfig __tests__ ios
.. .gitattributes android node_modules
.babelrc .gitignore index.android.js package.json
.buckconfig .watchmanconfig index.ios.js yarn.lock
- Changed .flowconfig, ran 'react-native upgrade'. Saw a prompt "Do you want to overwrite .flowconfig", tried answering first 'n' and then 'y'. When answering 'y' the file was overwritten by the version from the template as expected.

Summary:
Moves from CSSNodeDEPRECATED to CSSNode. This has shown to be a huge performance win for layout time within FB.
This is BREAKING because CSSNode contains bug fixes that were not migrated to CSSNodeDEPRECATED which may change the way your layout appears. The most common of these by far involves `flex: 1`.
Previously, developers had to put `flex: 1` in many places it didn't belong in order to work around a bug in css-layout. Now `flex: 1` is treated properly and, unfortunately, this means that your layout may no longer look correct. Specifically, you may see that your layout looks collapsed, or children don't render. The fix is to simply remove `flex: 1` from those containers.
