This reverts commit 50cbeca9.

Reason for revert: speculative revert for https://ci.chromium.org/ui/p/v8/builders/ci/V8%20Linux64%20TSAN%20-%20no-concurrent-marking/3824/overview

Original change's description:
> [codegen] Use builtin calls for TSANRelaxedStore
>
> Instead of calling the C function directly from codegen, we call a
> builtin that calls the C function. This is done to encapsulate the
> push/pop registers in the code in the builtin.
