Description
The Babel compiler contains a script called browser.js (or browser.min.js for the minified version) that causes a "method code too large" exception in Nashorn.

http://dev.clojure.org/jira/browse/CLJS-1322

I tracked the problem down to a function with a huge nested object literal.

To reproduce: 

> jjs babel-min.js

Comments
We currently only split array literals, but not object literals. Obviously we should split those, too.
