Issue #304 - gc_copy_obj must to populate bignums

Browse source 
Even without bignums in the nursery we still need this code in place since gc_alloc calls it, and otherwise all of the callers would need to ensure bignums are properly initialized. There may be an opportunity here for optimization, but let's make sure everything works first!
