Fix issue 191:

Browse Source 
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.
