JIT Sparse Function Table random crash fix (#319)

A couple of games have random crashing with the JIT Sparse Ftable changes, and it seems to have been caused by an insufficient int size returned by `AddressTableLevel#GetValue(ulong address)`.
It was 32 bits (Int32), but the GiantBlock (which is the current address table impl) uses potentially 36 bits for the first level.
