      Keep prototype maps in dictionary mode until ICs see them · be0494ba
      jkummerow authored
      Adding properties to prototypes is faster when we don't force their
      maps into fast mode yet. Once a prototype shows up in the IC system,
      its setup phase is likely over, and it makes sense to transition it
      to fast properties.
      This patch speeds up the microbenchmark in the bug by 20x.
      Octane-Typescript sees a 3% improvement.

      [proxies] use [[GetPrototypeOf]] trap in for-in key accumulation · 2efc1381
      cbruni authored
      With the recent spec change removing the [[Enumerate]] internal method, we now
      have to walk the complete prototype chain. This implies that we call the
      [[GetPrototypeOf]] trap on proxies.
      
      As a secondary change we now trigger the [[GetOwnProperty]] trap for the for-in
      filter step to see whether the properties are still enumerable. Before we did this
      in the key-accumulation phase. This way we slightly reduce the number of traps
      invoked. Whilst this is not ideal, it comes closer to the Spec's example
      implementation.
