This reverts commit ab089c78.

Reason for revert: Breaking GC stress (https://ci.chromium.org/p/v8/builders/ci/V8%20Linux64%20GC%20Stress%20-%20custom%20snapshot/27523)

Original change's description:
> [turbofan] Prepare for moving part of CreateGraph into the background
> 
> - Pass Refs, not Handles, to graph builder, and drop bytecode array argument
>   (get it from SFI instead).
> - Add some fields to FeedbackVectorRef that are needed to avoid heap access
>   in BytecodeGraphBuilderPhase.
> - Rename FeedbackVectorRef's SerializeSlots to Serialize, since it's more
>   than just the feedback slots.
> - Rearrange the last steps in PipelineCompilationJob::PrepareJobImpl such
>   that CreateGraph is last.
>
