David Aurelio b8da6a2963 Wait for the modules directory to be created before writing module files
Summary: Typo: the operation of writing module files to a common sub-directory didn?t wait until that directory was created, because `Promise.all` was invoked directly as argument to `.then()`, rather than putting it in a lambda function.

Martín Bigio 8edc35004c Move preloaded modules to startup code section
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.

David Aurelio 5b5a89aefa Add sourcemap support for asset-based random access bundles
Summary:This adds support for source maps that can be used for “random access modules” / “unbundles”

- source maps contain an extra custom field: `x_facebook_offsets`
- this field maps module IDs to line offsets
- the source map is built as if all files were concatenated

Decoding/symbolication works as follows:
- when decoding a stack trace, and a stack frame comes from a filename that contains only numbers and ends with `.js`, look up the additionally needed line offset in the offset map and add it to the original line of the stack frame.
- consume the source map as usual

David Aurelio 06b5bda349 Bring back "Use numeric identifiers when building a bundle"
Summary:This brings back "Use numeric identifiers when building a bundle", previously backed out.
This version passes on the correct entry module name to code that decides transform options.

Original Description:
Since the combination of node and haste modules (and modules that can be required as both node and haste module) can lead to situations where it’s impossible to decide an unambiguous module identifier, this diff switches all module ids to integers. Each integer maps to an absolute path to a JS file on disk.

We also had a problem, where haste modules outside and inside node_modules could end up with the same module identifier.

This problem has not manifested yet, because the last definition of a module wins. It becomes a problem when writing file-based unbundle modules to disk: the same file might be written to concurrently, leading to invalid code.

Using indexed modules will also help indexed file unbundles, as we can encode module IDs as integers rather than scanning string IDs.
