fedor 15a0ace533 heap: make array buffer maps disjoint 
Remove intersection from the `std::map`s representing current live
ArrayBuffers. While being simpler to understand, it poses significant
performance issue for the active ArrayBuffer users (like node.js).

Store buffers separately, and process them together during mark-sweep
phase.

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/*
