RFR: 8275318: loaded_classes_do may see ArrayKlass before InstanceKlass is loaded [v2]

[Ioi Lam]

> When a shared class K is restored, all of its archived array classes K[], K[][], etc, are also restored as well. Such restored classes are placed in the ClassLoaderData::_klasses list.
> 
> For safety, ClassLoaderData::loaded_classes_do() should skip all these classes until K is marked as "loaded".
