in allowing more flexible compilation and to simplify builtins lookup. 

This changes a number of places where code objects are assigned to
SharedFunctionInfo objects to also assign this code object to the
JSFunction. In addition, the code flushing is changed slightly to
accomodate this (we need to flush the code from functions pointing to
SharedFunctionInfo objects that has already been flushed).

Eventually indexed property query callbacks will return attributes
(as an integer) or an empty handle if property is not intercepted.

To gradually migrate to this new API, USE_NEW_QUERY_CALLBACK
macro would control if old or new style API is used.

So the migration plan is:

1) introduce new API which should be explictily enabled;
2) switch to new API defining USE_NEW_QUERY_CALLBACK before
include of <v8.h> (that would require changes to client code as well)
3) remove old API from v8
4) remove #define USE_NEW_QUERY_CALLBACK from clients.

I could not find a way to introduce simple yet useful assertions,
so I removed the assertions that broke tests.

The new patch just fixes the actual problem (GC triggered while raw pointers
are held in LookupResult).

string which holds only ascii chars and second is an empty string.  In this case we
would return first which is not AsciiRepresentation(), however cons is.
