Summary Improve variable resolution order on window

WebKit's variable resolution order on window has caused a number of bugs for the Closure Compiler. See http://code.google.com/p/chromium/issues/detail?id=80591 for more details of the case that keeps biting them. Also see http://lists.w3.org/Archives/Public/public-webapps/2011AprJun/0389.html and http://lists.w3.org/Archives/Public/public-script-coord/2012JanMar/0010.html for discussion on standardizing this. The discussion is not quite done, but it seems likely the WebKit/JSC/V8 will need to change.

I looked at a CL for this bug and yes it does require a v8 change for v8-based webkit browsers.

OK. This is resolved now. http://lists.w3.org/Archives/Public/public-script-coord/2012JanMar/0104.html

V8 has fixed this (behind a flag) but since all WebIDL attributes are implemented as own properties on the global object we need to fix bug 49739 to get non configurable properties to work correctly.
