RFR: 8231270: ZGC: Remove ZAddressSpace* and ZAddressReserved*

[Stefan Karlsson]

Looks good.

-XX:+VerifyOops has bit-rottened so I think it's OK to provide a nop 
implementation with:
Universe::calculate_verify_data((HeapWord*)0, (HeapWord*)UINTPTR_MAX);

but we might want to create an RFE to provide a better bit-mask if 
VerifyOops is fixed.

Thanks,
