Original commit message:

    tools,src: refloat forbid usage of v8::Persistent

    `v8::Persistent` comes with the surprising catch that it requires
    manual cleanup. `v8::Global` doesn’t, making it easier to use,
    and additionally provides move semantics. New code should always
    use `v8::Global`.
