Summary: AspectRatio is a new addition and soon after introduction we noticed use cases which is did not support. Specifically we wanted to support a node being as large as possible within a container while maintaining an arbitrary aspect ratio. This was not possible due to the low priority of AspectRatio, by increasing the priority of AspectRatio this is now possible as FlexGrow will grow an item to fit its parent unless the AspectRatio makes it too big in the cross axis, the AspectRatio will now override the FlexGrow in the main axis in that case.

Summary:
`JSIndexedRAMBundle` used to read scripts including the terminating null bytes. That worked on iOS, but not on Android, where we have an ascii-only optimization.
This changes that behavior to only read the actual script data excluding the terminal null.

Summary:
The C++ standard requires that when a function is used in a template it's prototype needs to be defined not only before the template specialization, but also before the template itself.
Because of that one needs to (in certain compilers) be aware of the proper order of includes so that the function prototype is defined before the JSCExecutor.h is included.
As a workaround the toValue might be written as a template (ValueEncoder<T>::toValue) defined in JSCExecutor.h instead of being an non-existing symbol.
Thanks to that the JSCExecutor.h does not have to be included before the specialization of the ValueEncoder template.

Summary:
To make React Native play nicely with our internal build infrastructure we need to properly namespace all of our header includes.
Where previously you could do `#import "RCTBridge.h"`, you must now write this as `#import <React/RCTBridge.h>`. If your xcode project still has a custom header include path, both variants will likely continue to work, but for new projects, we're defaulting the header include path to `$(BUILT_PRODUCTS_DIR)/usr/local/include`, where the React and CSSLayout targets will copy a subset of headers too. To make Xcode copy headers phase work properly, you may need to add React as an explicit dependency to your app's scheme and disable "parallelize build".

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.

Introduces the inspector library supporting the Chrome Debugging Protocol for JavaScriptCore. Eventually this will mean that it is possible to attach

layer.
The main entry point (and the only exported header) is `Inspector.h`.
This diff only introduces the basics supporting the `Schema` and `Inspector` domains meaning it doesn't have any features yet. These will come in following
diffs.

Summary:
**Motivation**
I'm working on a project that uses React Native and needs to add direct synchronous bindings to native stuff through the JavaScriptCore C API. This is because it's performance-sensitive and would benefit from the quickest JS->C path. It does this using cross-platform C++ code that works on both iOS and Android. Most of the infrastructure for getting access to the JSC context is already in React Native actually, just had to add a few more things.
(lexs you mentioned to tag you in this pull request)
**Test plan**
Modify the JavaScriptCore context through the `JSContextRef` returned (eg. add an object at global scope) and verify that it exists in JavaScript.

Summary:
We have a lot of small-ish calls to JSC and within the bridge that add up during TTI. This gives us a way to measure them in aggregate in a reasonable way.
From the comments:
MicroProfiler is a performance profiler for measuring the cumulative impact of
a large number of small-ish calls. This is normally a problem for standard profilers
like Systrace because the overhead of the profiler itself skews the timings you
are able to collect. This is especially a problem when doing nested calls to
profiled functions, as the parent calls will contain the overhead of their profiling
plus the overhead of all their childrens' profiling.
MicroProfiler attempts to be low overhead by 1) aggregating timings in memory and
2) trying to remove estimated profiling overhead from the returned timings.
To remove estimated overhead, at the beginning of each trace we calculate the
average cost of profiling a no-op code section, as well as invoking the average
cost of invoking the system clock. The former is subtracted out for each child
profiler section that is invoked within a parent profiler section. The latter is
subtracted from each section, child or not.
The usage is similar to Systrace: you put a MICRO_PROFILER_BLOCK in the block you want to profile and C++ RAII will handle timing it.
After MicroProfiler::stopProfiling() is called, a table of tracing data is emitted
to glog (which shows up in logcat on Android).
