This feature makes it possible to associate data with a script and get it back when the script is compiled or when an event is handled. It was historically used by Chromium Dev Tools, but not any more. It is not used by node.js. Note: this has nothing to do with the preparse data, despite the confusing name. The preparse data is passed as ScriptData*. Note 2: This is the same as r19616 ( https://codereview.chromium.org/184403002/ ) with a unused variable fix in bootstrapper.cc.
