deps: cherry-pick 5005faed5 from V8 upstream

Original commit message:

    [turbofan] Improve representation selection for type guard.

    This takes into account the type of the type guard when choosing
    representation for a node. To make the representation changes
    unambiguous, we pass the restricted type to the changer.
