For dumping the number of objects and size of objects alive after the
last gc into chrome://tracing memory dumps, this CL adds new api to
get these number for each isolate.

Note: Chrome should be run with --js-flags='--track_gc_object_stats

During inlining we should pay attention to only rewire the outer frame
states of the inlinee, but leave any inner frame states of the inlinee
untouched.  Otherwise we might run into trouble once we start caching
graphs, or do getter/setter inlining.

We need to treat the messages from such script resource as opaque.

The functions of strong classes are born non extensible. But, when
the class is created we need to add an own private symbol representing

Like for the hidden_string property, we allow adding private own
