Make sure to use the correct context for eval checks

We can't assume that there's no entered context during microtask
execution. We also can't assume that we'll never enter an context during
microtask execution either.

We can however assume that we don't execute microtasks recursively, so
remembering the length of the entered context stack is enough to decide
which context to use.

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/*
