verwaest 01b8e7c7f6 Throw TypeError when reading global references through a JSProxy 
Allowing global references to be read through a proxy results in cross-origin information leaks. The ES6 spec currently does not mitigate this in any way. This CL adds a workaround that's easy for V8: throw whenever an unresolved reference would result in a proxy trap to be fired. I'm landing this so we can move forwards with staging proxies without putting users of --harmony at risk.

Getting the Code

Checkout depot tools, and run

    fetch v8

This will checkout V8 into the directory v8 and fetch all of its dependencies. To stay up to date, run

    git pull origin
    gclient sync

For fetching all branches, add the following into your remote configuration in .git/config:

    fetch = +refs/branch-heads/*:refs/remotes/branch-heads/*
    fetch = +refs/tags/*:refs/tags/*
