mbrandy f53fda63eb PPC: Remove register index/code indirection 
Port 5cf1c0bcf6

Original commit message:
    Previous to this patch, both the lithium and TurboFan register
    allocators tracked allocated registers by "indices", rather than
    the register codes used elsewhere in the runtime. This patch
    ensures that codes are used everywhere, and in the process cleans
    up a bunch of redundant code and adds more structure to how the
    set of allocatable registers is defined.

    Some highlights of changes:

    * TurboFan's RegisterConfiguration class moved to V8's top level
      so that it can be shared with Crankshaft.
    * Various "ToAllocationIndex" and related methods removed.
    * Code that can be easily shared between Register classes on
      different platforms is now shared.
    * The list of allocatable registers on each platform is declared
      as a list rather than implicitly via the register index <->
      code mapping.

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/*

Contributing

Please follow the instructions mentioned on the V8 wiki.
