Tadeu Zagallo 0b46a0c13b Add a naive WPO implementation
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.
