1596b015ff [proxies] Support proxies in JSON.parse and JSON.stringify. 
This CL tries to correctly support the following:
- stringifying a proxy,
- stringifying with a proxy as replacer (callable or arraylike),
- stringifying with a replacer that returns a proxy,
- parsing with a callable proxy as reviver,
- parsing with a reviver that inserts proxies into the object,
- and whatever else you can imagine.

This also fixes some bugs observable without proxies.

a5380fe9ed JSON.parse: properly deal with reviver result 
When the reviver returns undefined, the property in question must be deleted
even for arrays.  So far this only happened for non-array objects.

Also change the property enumeration to be spec-conformant, which is observable when the reviver modifies its "this" object directly.  There are a few further issues that need to be addressed in a separate CL.

ce1e10f5fc Make __proto__ a foreign callback on Object.prototype. 
This moves the __proto__ property to Object.prototype and turns it into
a callback property actually present in the descriptor array as opposed
to a hack in the properties lookup. For now it still is a "magic" data
property using foreign callbacks and not an accessor property visible to
JavaScript.

The second effect of this change is that JSON.parse() no longer treats
the __proto__ property specially, it will be defined as any other data
property. Note that object literals still have their special handling.
