This reverts commit 5bdffcd32e.
Reason for revert: Failures on DBC, timeouts on hot reload and opt counter stress bots.
Original change's description:
> [vm] Add a simple compactor.
>
> The compactor copies all live objects in old space to fresh pages, places forwarding pointers in the old objects, forwards all the pointers, then frees the old pages. This has a high space overhead. It is not meant for use in production, but meant to test that the VM is properly set up to handle old-space objects moving.
>
> Large page objects and instruction objects are not moved.
>
