    [turbofan] Introduce CheckIf simplified operator. · 483291d2
    bmeurer authored
    This adds a new CheckIf operator and changes all direct uses of
    DeoptimizeIf and DeoptimizeUnless on the JavaScript level to use
    CheckIf (or one of the more concrete check operators) instead.
    This way we do not depend on particular frame states, but the
    effect/control linearizer will assign an appropriate frame
    state instead.
