It also renames {type,obj}ArrayKlass->allocate functions to allocate_klass and allocate_instance so it's more clear which allocation it's doing and to match InstanceKlass allocate functions, and makes these functions private with friends for Deoptimization and oopFactory.  For JEP 401, arrays are being extended to support new formats and attributes and this reduces the call sites.
