[v8-extras] Harden `resolvePromise()` and `rejectPromise()`.

The V8 Extras API provides `resolvePromise()` and `rejectPromise()`
functions that bypass the safety net of the resolve/reject closures
that you get from using the Promise constructor. So it's the
responsibility of the user to make sure that the promises are still
pending. This adds release mode checking and hard aborts to make
sure we catch misuse of these APIs early.

This also turns the DCHECK's in the C++ implementation into actual
CHECK's to make sure we crash hard if the invariants are violated.

V8 JavaScript Engine

V8 is Google's open source JavaScript engine.

V8 implements ECMAScript as specified in ECMA-262.

V8 is written in C++ and is used in Google Chrome, the open source browser from Google.

V8 can run standalone, or can be embedded into any C++ application.

V8 Project page: https://github.com/v8/v8/wiki

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/*
