This reverts commit dcac02ee.

Reason for revert: TSAN discovered issue with cleaning invalidated slots in sweeper threads and inserting new slots in the main thread.

Original change's description:
> Use list of invalidated objects for old-to-new refs
> 
> Instead of inserting "deletion" entries into the store buffer, keep
> a list of invalidated objects to filter out invalid old-to-new slots.
