c6e42e1bfa Fix initial prototype of WeakMap function.
The bootstrapper accidentally overwrote the constructor property of the Object
prototype because it used initial_object_prototype() as prototype for WeakMap.
Unfortunately this is not possible for experimental natives because they are
installed after the snapshot initialization finished.

c6c504f8b6 Parse harmony let declarations.
Implementation of the harmony block scoped let bindings as proposed here:
http://wiki.ecmascript.org/doku.php?id=harmony:block_scoped_bindings

Changes to the syntax are explained there. They are active under the
harmony_block_scoping_ flag in the parser.

d640d8d913 Fix issue with prototype of WeakMap constructor.
The WeakMap constructor didn't have a unique prototype, so it shared one with
Object. All WeakMap functions (including "get" and "set") were installed on
that prototype.

670f947a5c Implement set trap for proxies, and revamp class hierarchy in preparation:
- Introduce a class JSReceiver, that is a common superclass of JSObject and
  JSProxy. Use JSReceiver where appropriate (probably lots of places that we
  still have to migrate, but we will find those later with proxy test suite).

- Move appropriate methods to JSReceiver class (SetProperty,
  GetPropertyAttribute, Get/SetPrototype, Lookup, and so on).

- Introduce new JSFunctionProxy subclass of JSProxy. Currently only a stub.

- Overhaul enum InstanceType:
  * Introduce FIRST/LAST_SPEC_OBJECT_TYPE that ranges over all types that
    represent JS objects, and use that consistently to check language types.
  * Rename FIRST/LAST_JS_OBJECT_TYPE and FIRST/LAST_FUNCTION_CLASS_TYPE
    to FIRST/LAST_[NON]CALLABLE_SPEC_OBJECT_TYPE for clarity.
  * Eliminate the overlap over JS_REGEXP_TYPE.
  * Also replace FIRST_JS_OBJECT with FIRST_JS_RECEIVER, but only use it where
    we exclusively talk about the internal representation type.
  * Insert JS_PROXY and JS_FUNCTION_PROXY in the appropriate places.

- Fix all checks concerning classification, especially for functions, to
  use the CALLABLE_SPEC_OBJECT range (that includes funciton proxies).

- Handle proxies in SetProperty (that was the easiest part :) ).

- A few simple test cases.
