Summary:
This will allow consumers to supply their own transformer to all `react-native` cli commands by simply implementing `rn-cli.config.js` and overriding `getTransformModulePath()`. That way they don't have to fork various parts of the iOS and Android build system that React Native already provides just to add a `--transformer` command line argument.
**Test plan:** Applied this patch to the React Native version in my app, implemented `getTransformModulePath()` in my `rn-cli.config.js`, and verified that my custom transformer is invoked.

Summary:
Re: javache 's suggestions from https://github.com/facebook/react-native/pull/7878. Didn't want to deal with the merge conflict so I'm opening a separate PR. Here's the original justification:
If I want to set NODE_ENV to "baconator", I should be allowed to. Mutating global state that most devs assume to be immutable is just abysmal dev practice, especially since this mutation only happens when you're building for prod, not running on the simulator.
To test this, run env NODE_ENV=baconator ./gradlew assembleRelease with babel-plugin-transform-inline-environment-variables in your app/.babelrc. You'll see that the final app has NODE_ENV=production.
As a side note, running with babel-plugin-transform-inline-environment-variables in the top-level .babelrc crashes horribly with a compiler error.
For anybody who runs into this bug and doesn't feel like waiting for this to get merged, I wrote a quick babel plugin to remove assignments to process.env, which is sufficient to fix this issue.

Summary:
`react-native start` already ensures that the `--transformer` path is understood to be relative to CWD, not to the module that ends up importing that file. `react-native bundle` and `react-native dependencies` didn't up until this point.
**Test plan:** Ensured that `react-native bundle ... --transformer ./relative/path` works with this patch applied.

Summary:
Currently the `react-native bundle` has no option to reset the file cache. For example changing the .babelrc has no effect on the bundling process. `react-native start` has it already implemented, so this is just a small addition.
**Test plan (required)**
the issue:
- `react-native init` a new project
- run `react-native bundle` (should work as expected)
- create `.babelrc` with empty object ```{}```
- rerun `react-native bundle`
- should fail now with `Unexptected token` (no babel plugins configured)
- if not failing, your cache already hit (clear $TMPDIR to get the error)
- delete .babelrc and rerun `bundle`
- still failing, but it should went back to normal
- delete your $TMPDIR contents
- works again
The option `--reset-cache` should fix that

Summary:The logic when saving a bundle was flawed: we didn?t wait for promises returned by the `save` operation.

Summary:Make packager transform files before extracting their dependencies.
This allows us to extract dependencies added by transforms (and to avoid including them manually).
It also allows for better optimization and to get rid of the “whole program optimization” step:
This diff utilizes the new worker introduced in D2976677 / d94a567 – that means that minified builds inline the following variables:
- `__DEV__` → `false`
- `process.env.NODE_ENV` → `'production'`
- `Platform.OS` / `React.Platform.OS` → `'android'` / `'ios'`
and eliminates branches of conditionals with constant conditions. Dependency extraction happens only after that step, which means that production bundles don’t include any modules that are not used.

Passing around a `getTransformOptions` function doesn't really work with the CLI utils, so I'm changing this to `getTransformOptionsModulePath` instead, which can easily be injected in through `rn-cli.config.js`.

Summary: This adds a build option for using Prepack (an experimental packager) to
build a bundle. It doesn't actually take on the npm package dependency
because it's not published/open source (yet).
This will be used while we experiment and should be maintained as the
build system changes so that we can continue getting fresh builds.
I found that saveBundleAndMap and processBundle were over abstracted and
got in my way so I inlined it and removed the unit tests because the unit
test was testing trivial code that is likely to change interface.
I went with a separate build phase and a separate Bundle class even though
there are a lot of commonalities. I imagine that the requirements for
Prepack will continue to diverge. Especially for source maps but a larger
refactor could try to unify these a bit more. The fact that modules are
wrapped before the write phase seems to be an unfortunate architecture
that makes this difficult.

Summary: public
RFC: The minifier haven't been stripping dead-code, and it also can't kill unused
modules, so as a temporary solution this inlines `__DEV__`, kill dead branches
and kill dead modules. For now I'm just white-listing the dev variable, but we
could definitely do better than that, but as a temporary fix this should be
helpful.
I also intend to kill some dead variables, so we can kill unused requires,
although inline-requires can also fix it.

To improve cold start performance we want to be able to avoid decoding the bundle at all. To make that happen we need to be able to generate a bundle encoded on `ucs2`. This diff adds support for indicating the encoding the Packager should use for bundling.

We cannot remove `local-cli` because is referenced by the global cli explicitly. If we do so, people would have to upgrate this global thin cli which will cause some pain. So, lets move `private-cli` commands into `local-cli` instead.
