This reverts commit 2c096b53.

Reason for revert: speculative revert for https://ci.chromium.org/ui/p/v8/builders/ci/V8%20Linux64%20TSAN%20-%20no-concurrent-marking/3838/overview

Original change's description:
> [codegen] Add TSAN support for tagged stores in generated code
>
> Mimics the kArchStoreWithWriteBarrier store in generated code by having
> a relaxed store to the same address, with the same value. This is done
> in order for TSAN to see these stores from generated code.
>
> Since it is done only for kArchStoreWithWriteBarrier TSAN will see
> tagged stores only.
