      [builtins] Extend the @@species protector to guard Promises. · 79e91f0c
      Benedikt Meurer authored 
      Use this in the PromiseThen operation to skip the (expensive) lookup in
the SpeciesConstructor operation. This yields in a nice 3-5% improvement
on the bluebird and wikipedia benchmarks, and paves the way for inlining
certain Promise operations into TurboFan optimized code later.

On the micro-benchmark mentioned in the bug (from the findings doc), we
reduce the overall execution time by 25%, which makes sense given that
Promise.prototype.then spends a significant portion of it's time just
figuring out the appropriate constructor.

      Revert "Optimize TypedArraySpeciesCreate using SpeciesProtector of Array" · b131cc35
      Jakob Gruber authored 
      This reverts commit 8fbc6a05.

Reason for revert: https://crbug.com/800356

Original change's description:
> Optimize TypedArraySpeciesCreate using SpeciesProtector of Array
> 
> If there is no constructor or species updates on Array or TypedArrays,
> then skip lookups of constructor and species so that we can create a new
> typed array quickly. This path makes TA.p.slice() 4x faster in fast
> cases.
