rename --opt to ---turbofan, and --always-opt to --always-turbofan.

We have to take the slow path in Promise.all if context promise hooks
are set. The fast-path doesn't create intermediate promises by default.

The previously added perf-context Promise-hooks take a v8::Function as
arguments. However, the builtin code was only accepting JSFunctions
which causes cast errors.
Drive-by-fix: Directly pass nativeContext in more places.

This is a reland of d5457f5fb7
after a speculative revert.
Additionally it fixes an issue with throwing promise hooks.

This will enable Node.js to get much better performance from async_hooks
as currently PromiseHook delegates to C++ for the hook function and then
Node.js delegates it right back to JavaScript, introducing several
unnecessary barrier hops in code that gets called very, very frequently
in modern, promise-heavy applications.
This API mirrors the form of the original C++ function based PromiseHook
API, however it is intentionally separate to allow it to use JSFunctions
triggered within generated code to, as much as possible, avoid entering
runtime functions entirely.
Because PromiseHook has internal use also, beyond just the Node.js use,
I have opted to leave the existing API intact and keep this separate to
avoid conflicting with any possible behaviour expectations of other API
users.
The design ideas for this new API stemmed from discussion with some V8
team members at a previous Node.js Diagnostics Summit hosted by Google
in Munich, and the relevant documentation of the discussion can be found
here: https://docs.google.com/document/d/1g8OrG5lMIUhRn1zbkutgY83MiTSMx-0NHDs8Bf-nXxM/edit#heading=h.w1bavzz80l1e
