titzer 17001a05c8 [wasm] Introduce instance types for WebAssembly.* objects. 
This CL refactors the internal representation of JavaScript-exposed
WebAssembly objects to be more like other such objects in V8. By introducing
a new instance type for each of the JS-exposed types, we get more robust
typechecking without using embedder fields (which were previously used
when these objects where instance type JS_API_OBJECT).

In addition to the new instance types, the subclasses X of JSObject
(WasmInstanceObject, WasmMemoryObject, WasmModuleObject, WasmTableObject)
now have appropriate Is##X() methods on Object and are now robust.

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.

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/*
