X87: [builtins] Introduce proper Float64Cos and Float64Sin.

  port c781e83194031b337f8eafb42588a2e3d7440782 (r37072)

  original commit message:
  Import base::ieee754::cos() and base::ieee754::sin() from fdlibm and
  introduce Float64Cos and Float64Sin TurboFan operator based on that,
  similar to what we do for Float64Log. Rewrite Math.cos() and Math.sin()
  as TurboFan builtins and use those operators to also inline Math.cos()
  and Math.sin() into optimized TurboFan functions.
