      [es6] Reintroduce the instanceof operator in the backends. · 551e0aa1
      bmeurer authored
      This adds back the instanceof operator support in the backends and
      introduces a @@hasInstance protector cell on the isolate that guards the
      fast path for the InstanceOfStub. This way we recover the ~10%
      regression on Octane EarleyBoyer in Crankshaft and greatly improve
      TurboFan and Ignition performance of instanceof.
