mlippautz 555c961990 Revert of [heap] Switch to 500k pages (patchset #24 id:780001 of https://codereview.chromium.org/2013713003/ ) 
Reason for revert:
Failures on waterfall:

e.g. http://build.chromium.org/p/client.v8/builders/V8%20Linux64%20TSAN/builds/11134

Original issue's description:
> [heap] Switch to 500k pages
>
> - Decrease regular heap object size to 300k, keeping the same ration (60%)
>   between this limit and page size.
>
> In a follow up, we can now get rid of the new space border page while
> keeping the 1M minimum new space size.
>
> Some results (v8.infinite_scroll; 3 runs):
> - evacuate.avg: +15.3% (1.4->1.2)
> - evacuate.max: +24.4% (2.4->1.8)

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/*
