machenbach 789b0ad77a Revert of [builtins] Introduce proper Float64Exp operator. (patchset #5 id:80001 of https://codereview.chromium.org/2077533002/ ) 
Reason for revert:
[Sheriff] Leads to some different rounding as it seems in some audio layout tests. Please rebase upstream first if intended:
https://build.chromium.org/p/client.v8.fyi/builders/V8-Blink%20Linux%2064/builds/7508

Original issue's description:
> [builtins] Introduce proper Float64Exp operator.
>
> Import base::ieee754::exp() from FreeBSD msun and introduce a Float64Exp
> TurboFan operator based on that, similar to what we do for Float64Log.
> Rewrite Math.exp() as TurboFan builtin and use that operator to also
> inline Math.exp() into optimized TurboFan functions.
