The new option controls a static member in InstanceKlass that's consulted to determine whether the finalization machinery is activated for instances when a class is loaded. A new native method is added so that this state can be queried from Java. This is used to control whether a finalizer thread is created and to disable the `System` and `Runtime::runFinalization` methods. Includes tests for the above.

Hi Stuart,

This all looks fine to me. The hotspot part needs a second reviewer (especially as I contributed a chunk of that code :) ).

Thanks,
David
