This changes object_id from being based on the objects location in memory (or a nearby memory location in the case of a conflict) to be based on an always increasing number. This number is a Ruby Integer which allows it to overflow the size of a pointer without issue (very unlikely to happen in real programs especially on 64-bit, but a nice guarantee). This changes obj_to_id_tbl and id_to_obj_tbl to both be maps of Ruby objects to Ruby objects (previously they were Ruby object to C integer) which simplifies updating them after compaction as we can run them through gc_update_table_refs.
