Z Nguyen-Huu e3bbf2bf24 [turbofan] Reduce consecutive machine multiplication with constants
There exists such optimization for additions but not for multiplication.

This adds optimizations that apply the reductions
  (x * Int32Constant(a)) * Int32Constant(b)) => x * Int32Constant(a * b)
  (x * Int64Constant(a)) * Int64Constant(b)) => x * Int64Constant(a * b)
to the TurboFan graph.
