[builtins] Introduce proper Float64Cos and Float64Sin.

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.

[builtins] Introduce proper Float64Cos and Float64Sin.

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.
