Original issue's description:
> [Atomics] code stubs for atomic operations
>
> * New atomic code stubs for x64, ia32, arm, arm64
> * Add convenience functions JumpIfNotValidSmiValue, JumpIfUintNotValidSmiValue
>   to macro-assembler-ia32 (API based on x64 macro assembler)
> * Remove runtime implementation of Atomics.load, the code stub should always be
>   called instead
> * Add new test to mjsunit atomics test; check that Smi values of different
>   sizes are supported when possible, else fall back to HeapNumbers
>
> These changes were needed to add another codestub:
> * Bump kStubMajorKeyBits from 7 to 8
> * Reduce ScriptContextFieldStub::kSlotIndexBits from 13 to 12

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.

    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/*
