jarin ef35f11c43 Remove the template magic from types.(h|cc), remove types-inl.h. 
This CL removes the Config templatization from the types. It is not
necessary anymore, after the HeapTypes have been removed.

The CL also changes the type hierarchy - the specific type kinds are
not inner classes of the Type class and they do not inherit from Type.
This is partly because it seems impossible to make this work without
templates. Instead, a new TypeBase class is introduced and all the
structural (i.e., non-bitset) types inherit from it.

The bitset type still requires the bit-munging hack and some nasty
reinterpret-casts to pretend bitsets are of type Type*. Additionally,
there is now the same hack for TypeBase - all pointers to the sub-types
of TypeBase are reinterpret-casted to Type*. This is to keep the type
constructors in inline method definitions (although it is unclear how
much that actually buys us).

In future, we would like to move to a model where we encapsulate Type*
into a class (or possibly use Type where we used to use Type*). This
would loosen the coupling between bitset size and pointer size, and
eventually we would be able to have more bits.

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/*
