Tadeu Zagallo 02ded6d0bb Preserve all return registers on x86_64 trampoline
Summary:
public

Only the first quad-word and floating point return registers were being preserved,
make sure to preserve the 2nd ones as well (`%rdx` and `%xmm1`)

Nick Lockwood 060664fd3d Refactored module access to allow for lazy loading
Summary: public

The `bridge.modules` dictionary provides access to all native modules, but this API requires that every module is initialized in advance so that any module can be accessed.

This diff introduces a better API that will allow modules to be initialized lazily as they are needed, and deprecates `bridge.modules` (modules that use it will still work, but should be rewritten to use `bridge.moduleClasses` or `-[bridge moduleForName/Class:` instead.

The rules are now as follows:

* Any module that overrides `init` or `setBridge:` will be initialized on the main thread when the bridge is created
* Any module that implements `constantsToExport:` will be initialized later when the config is exported (the module itself will be initialized on a background queue, but  `constantsToExport:` will still be called on the main thread.
* All other modules will be initialized lazily when a method is first called on them.

These rules may seem slightly arcane, but they have the advantage of not violating any assumptions that may have been made by existing code - any module written under the original assumption that it would be initialized synchronously on the main thread when the bridge is created should still function exactly the same, but modules that avoid overriding `init` or `setBridge:` will now be loaded lazily.

I've rewritten most of the standard modules to take advantage of this new lazy loading, with the following results:

Out of the 65 modules included in UIExplorer:

* 16 are initialized on the main thread when the bridge is created
* A further 8 are initialized when the config is exported to JS
* The remaining 41 will be initialized lazily on-demand

Summary: public

`%xmm` registers weren't being preserved what would cause eventual weird issues

Tadeu Zagallo 0f92639a96 Prevent RCTProfileTrampoline from getting stripped
Summary: public

I was using `dlsym` as a more elegant way of checking if the function was defined
to prevent crashes if running on an unsupported architecture, but Xcode might
strip the symbol, even with `.no_dead_strip`, if there's no references to the
compilation unit at all.

Replace it with an ugly `#if` that checks if it's any of the supported targets
and extern the function prototype.

Tadeu Zagallo 89c1747c33 Implement asm trampoline rather forwardInvocation
Summary: public

The profiler overrides all the methods of all the BridgeModules, and in order to
`start` and `end` the profiler at the function invocation time it used `NSInvocation`,
which is slow.

Replace it with a simple assembly method based on `objc_msgSend`.
