Recognize Inner Scoped Types Exported as a Property on the Global Object

A lot of libraries I come across are almost compatible with closure-compiler. Usually the first step is to remove the IIFE that the code has.

I'd like the compiler to do this for me. A couple of options I've thought of:
1. Custom pass, possibly with a command line flag option.
2. Attempt to treat global IIFEs in a similar manner to goog.scope calls.
