This reverts commit 79d63a5e.

Reason for revert: Breaks predictable: https://ci.chromium.org/ui/p/v8/builders/ci/V8%20Linux%20-%20predictable/36887/overview

Original change's description:
> [wasm] Remove all implications from --predictable
>
> In predictable mode, we want to execute the same code as otherwise,
> modulo timing. Hence remove any implications which change behaviour
> (like tier-up or asynchronous compilation).
> Note that --predictable is a debugging flag, so the configurations does
> not need to "make sense" in production.
