bmeurer 3fbbfc38c2 [turbofan] Sanitize typing rules for function calls. 
Currently we (mostly) infer FunctionType for JSFunction constants, and
match the FunctionType in the typing rule for JSCallFunction. This has
several drawbacks for JavaScript, especially we don't have Constant
types for global functions (i.e. String, Object, Reflect and friends).
Plus the FunctionType magic doesn't actually buy us anything. So this
changes the typing rule for HeapConstant constant to actually infer
Constant types for JSFunction objects and moves the recognition of
builtin functions to the typing rule for JSCallFunction.

Also adapts the specialized lowering in JSTypedLowering to Constant
functions instead of FunctionType, which has the additional advantage
that we can do the receiver wrapping/converting based on the (known)
SharedFunctionInfo.

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.
