Nico Hartmann cb9bf85b2e Revert "[heap] Ensure all old-to-shared slots are recorded" 
This reverts commit c3a5c5b1e0.

Reason for revert: https://ci.chromium.org/ui/p/v8/builders/ci/V8%20Linux64%20-%20shared/21941/overview

Original change's description:
> [heap] Ensure all old-to-shared slots are recorded
>
> This CL adds verification of the old-to-shared remembered set to
> --verify-heap. During shared GCs client heaps will be scanned for
> references into the shared heap, this CL will CHECK that every found
> slot is contained in the old-to-shared remembered set. After this
> gets a bit more stable, the full heap iteration can be dropped and we
> can fully rely on the remembered set instead.
