This reverts commit 87f71769c5.
Reason for revert: Performance regressions https://chromeperf.appspot.com/group_report?rev=46185
Original change's description:
> [ignition] Merge bytecode array builder and writer
>
> Move bytecode array writing logic into the array builder, allowing us to
> remove the bytecode array writer and bytecode node, and convert runtime
> operand writing to compile-time bytecode operand writing using the
> information statically known at compile time.
