Since JDK-8350550, we have the property that:
Every live heap object that can be found by the garbage collector have a valid class (*), even if the object originates from the AOT cache.
This allows the following check to be removed from ClaimMetadataVisitingOopIterateClosure::do_klass()
https://github.com/openjdk/jdk/commit/fd30ae988bc512b5d2a5a3fd1bc1ed351af974c7#diff-9512406aa5bffbef807aa26007f54e2bfb6b0635e1829aa77bf483bdfd342c8cL54-L59
* valid class means: the class has be loaded and Klass::class_loader_data() is not null
We should add an assertion in debug builds to validate this property for the AOTMappedHeapLoader.
