The issue is that the extension object is a normal javascript object
on which assignments to __proto__ changes the prototype chain.

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.

Avoiding the assumption that the pc pointer of RelocInfo points to the word containing the target address. It wasn't true for ARM. (One step closer to serialization on ARM).

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.

Factored the generation of JSON serialization from beeing part of the mirror objects into a seperate class. The purpose of this is to make it easier to change the serialization to contain object identification and references.

categorize the ticks that occur within generated code and thereby show
more detailed information about where time is spent in generated code.

  are conservative in the sense that they only detect
  failure with certainty.  Checks can do 2 or 4 characters
