	<rdar://problem/3908017> REGRESSION (172-173): assertion in ObjectImp::construct trying to create JS error (24hourfitness.com)

	The fix was to implement copy constructor and assignment operator,
	the ones that worked on the base class did not replace the
	defaults apparently!

        * kjs/protect.h:
        (KJS::ProtectedValue::ProtectedValue):
        (KJS::ProtectedValue::operator=):
        (KJS::ProtectedObject::ProtectedObject):
        (KJS::ProtectedObject::operator=):

	Also fixed a bug in the GC test mode that compares the results of
	the old collector and the new collector.

	* kjs/value.cpp:
        (ValueImp::mark):
