machenbach f68cd33bdd Revert of [turbofan] greedy: heuristic for memory operands (patchset #2 id:40001 of https://codereview.chromium.org/1306823005/ ) 
Reason for revert:
[Sheriff] Breaks test with greedy allocator:
http://build.chromium.org/p/client.v8/builders/V8%20Linux%20-%20debug%20-%20greedy%20allocator/builds/1318

Original issue's description:
> [turbofan] greedy: heuristic for memory operands
>
> When we have a memory operand (HasSpillOperand() == true), and it
> doesn't need a register immediately, split in an optimal position, which
> is outside the outermost possible loop - just like Linear does.
>
> This results in some modest improvements in perf, when compared
> to baseline greedy. In particular Jetstream zlib x64: 4.66%, Life
> (Emscripten x64) 11%; largest regression is in AreWeFastYet x64: 8%
> and Corrections (Emsccripten x32) 10%

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/*
