zhengxing.li 37d1dd823b X87: [runtime] Introduce dedicated JSBoundFunction to represent bound functions. 
port 97def8070c (r33044)

  original commit message:
  According to the ES2015 specification, bound functions are exotic
  objects, and thus don't need to be implemented as JSFunctions. So
  we introduce a new JSBoundFunction type to represent bound functions
  and make them optimizable. This already improves the performance of
  calling or constructing bound functions by 10-100x depending on the
  use case because we avoid the crazy dance between JavaScript and C++
  that was implemented in v8natives.js previously.

  There's still room for improvement in the performance of actually
  creating bound functions, which is also relevant in practice, but
  we already have a plan how to accomplish that later.

  The mips/mips64 ports were contributed by akos.palfi@imgtec.com.

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/*
