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.
Fixes#4185

Summary:
Currently, the CLI is not passing the sourceMapURL option to the bundler, so source maps are output as "null".

Summary:
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.

Summary: public
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.

Summary: public
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.
