2cb36759ba Fix issue 6264 with a test case.
The problem is that Disable/EnableAccessCheck on an object may chnage its constructor's behavior
if object's map is the same as constructor's initial map. By copying maps, the constructor's
initial map is not changed.

6bc1d40a57 Added handles to the mirror objects. When a mirror for an object is created it is assigned a numeric handle. Handles are used to make a 1:1 correspondence between objects and mirrors. Currently the mirrors are cached in a JavaScript array and when creating a mirror this cache is checked to see if a mirror already exists for the object. This cache is cleared when leaving the debugger.
Changed the serialization format to take advantage of these handles. When an object is serialized referenced objects are represented just by their handle id serialized as '{ref:<handle>}'. During serialization the referenced handles are collected and the serializer can provide a serialization of all the referenced objects.

Removed the special handling of array properties. Indexed properties and the length property are now rendered as named properties in the serialization.

Removed the special serialization handling of RegExp properties. The properties 'source', 'global', 'ignoreCase' and 'multiline' are serialized with the rest of the properties.

Changed a lot of tests to handle the changed format.

384b0a5408 Fix issue 191:
http://code.google.com/p/v8/issues/detail?id=191

Accessor setters should not be called for eval-introduced context
extension objects.

This change fixes the issue, but I think it is time to separate out
the lookup routines for eval-introduced context extension objects.
There is no reason to use the general lookup routines for this.  I'll
do that in a separate changelist.

25112aba44 Refactored the mirror representation of properties. Removed the AssessorMirror and InterceptorPropertyMirror and moved all reflection for properties to PropertyMirror. From a PropertyMirror it can be checked whether a property has getter/setter defined in JavaScript and information on the getter/setter functions are now available. If calling the getter resulted in an exception this is reflected as well.
Properties from interceptors are also reflected through PropertyMirror as the distinction did not make sense seen from a JavaScript debugging perspective. The isNative function on a PropertyMirror can be used to check whether a property is defined natively by the host (or V8).

Simplified the local property lookup in the debug runtime call to just call GetProperty as the property is known to be a local property.

12854e6c67 Allocate as many object-literal properties as possible inobject.
This can lead to large objects which wastes a lot of space if we normalize properties.  We therfore clear the inobject properties when normalizing properties.  This is done by adjusting the instance size in the new map and overwriting the inobject properties with a filler.
