If the object being finalized does not have an object ID, then we don't
need to insert into the object ID table, we can simply just allocate a
new object ID by bumping the next_object_id counter. This speeds up
finalization for objects that don't have an object ID. For example, the
following script now runs faster:
1_000_000.times do
o = Object.new
ObjectSpace.define_finalizer(o) {}
end

Range (min … max): 1.441 s … 1.503 s 10 runs
After:
Time (mean ± σ): 1.199 s ± 0.015 s [User: 1.103 s, System: 0.086 s]
