Summary:
This is a very hacky solution to make reloads from packager faster for simple file changes.
Simple means that no dependencies have changed, otherwise packager will abort the attempt to update and fall back to the usual rebuilding method.
In principle, this change avoids re-walking and analyzing the whole dependency tree, and just updates modules in existing bundles.

Summary:We found that moving the preloaded modules to the startup section of the RAM Bundle improves TTI quite a bit by saving lots of through the bridge calls and injecting multiple modules at once on JSC. However, doing this on a non hacky way required a lot of work. The main changes this diff does are:
- Add to `BundleBase` additional bundling options. This options are fetched based on the entry file we're building by invoking a module that exports a function (`getBundleOptionsModulePath`).
- Implement `BundleOptions` module to include the `numPreloadedModules` attribute as a bundle additional option. This value is computed by getting the dependencies the entry file has and looking for the first module that exports a module we don't want to preload. The `numPreloadedModules` attribute is then used to decide where to splice the array of modules.
- Additional kung fu to make sure sourcemaps work for both preloaded and non preloaded modules.

Summary:After starting to minify off the main process, the order of module transport objects in `Bundle` instances became less deterministic.
These changes guarantee that module transports appear in addition order, not in order of minification completion.

Summary:
The bundler class had duplicated code and parts that were hard to follow, because functions accepted heterogenous arguments, leading to a lot of conditionals.
This commit tries to remove duplication between build steps of different type of bundles, and by accepting less different types of arguments. These differences are now handled further up the call stack.

Summary:

To make sourcemaps work on Hot Loading work, we'll need to be able to serve them for each module that is dynamically replaced. To do so we introduced a new parameter to the bundler, namely `entryModuleOnly` to decide whether or not to process the full dependency tree or just the module associated to the entry file. Also we need to add `//sourceMappingURL` to the HMR updates so that in case of an error the runtime retrieves the sourcemaps for the file on which an error occurred from the server.
Finally, we need to refactor a bit how we load the HMR updates into JSC. Unfortunately, if the code is eval'ed when an error is thrown, the line and column number are missing. This is a bug/missing feature in JSC. To walkaround the issue we need to eval the code on native. This adds a bit of complexity to HMR as for both platforms we'll have to have a thin module to inject code but I don't see any other alternative. when debugging this is not needed as Chrome supports sourceMappingURLs on eval'ed code
