jgruber 6b7493a4d8 Revert of Use a custom Struct for stack trace storage (patchset #4 id:60001 of https://codereview.chromium.org/2230953002/ ) 
Reason for revert:
Performance regressions in Gameboy, Life, CodeLoad and others. See crbug.com/638210.

Original issue's description:
> Refactor data structures for simple stack traces
>
> Simple stack traces are captured through Isolate::CaptureSimpleStackTrace.
> Captured frames are stored in a FixedArray, which in turn is stored as a
> property (using a private symbol) on the error object itself. Actual formatting
> of the textual stack trace is done lazily when the user reads the stack
> property of the error object.
>
> This would involve many conversions back and forth between index-encoded raw
> data (receiver, function, offset and code), JS CallSite objects, and C++
> CallSite objects.
>
> This commit refactors the C++ CallSite class into a Struct class called
> StackTraceFrame, which is the new single point of truth frame information.
> Isolate::CaptureSimpleStackTrace stores an array of StackTraceFrames, and JS
> CallSite objects (now created only when the user specifies custom stack trace
> formatting through Error.prepareStackTrace) internally only store a reference
> to a StackTraceFrame.

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

    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/*
