chunyang.dai 56600a35a4 X87: Reimplement Maps and Sets in JS
port 909500aa1d (r27605)

original commit message:
    Previously, the only optimized code path for Maps and Sets was for String keys.
    This was achieved through an implementation of various complex operations
    in Hydrogen. This approach was neither scalable nor forward-compatible.

    This patch adds the necessary intrinsics to implement Maps and Sets almost entirely
    in JS. The added intrinsics are:

      %_FixedArrayGet
      %_FixedArraySet
      %_TheHole
      %_JSCollectionGetTable
      %_StringGetRawHashField

    With these additions, as well as a few changes to what's exposed as runtime functions,
    most of the C++ code backing Maps and Sets is gone (including both runtime code in
    objects.cc and Crankshaft in hydrogen.cc).

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://code.google.com/p/v8/

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/*
