improve allocation accounting for incremental mark

Add an assertion that allocated_bytes >= 0 in IncrementalMark::Step and then
make it pass. We were not being diligent in maintaining top_on_previous_step_
and as a result inaccurate, and even negative values of allocated_bytes were
being reported to Step.
