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
This is not only to put the files on a place where it makes more sense but also to allow to use ES6 features on them as `/packager` is not whitelisted on `babel`.

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.
