X87: [turbofan] Introduce Float64Pow and NumberPow operators. port e607e12ea0a706a0b8cb109e95f923426094dc09 (r37323) original commit message: Introduce a new machine operator Float64Pow that for now is backed by the existing MathPowStub to start the unification of Math.pow, and at the same time address the main performance issue that TurboFan still has with the imaging-darkroom benchmark in Kraken. Also migrate the Math.pow builtin itself to a TurboFan builtin and remove a few hundred lines of hand-written platform code for special handling of the fullcodegen Math.pow version.
