A version of the spec change from
https://github.com/tc39/ecma262/pull/988, but applied to the
Async-from-Sync iterator type.

This change does not modify generated bytecode (but maybe it should to
take advantage of load IC feedback for loading "next"). Doing this grows
bytecode by quite a bit, since it's necessary to throw-if-not-an-object
before loading "next" (which currently gets to live in a code stub
instead).

Copied as-is modulo compile tweaks from Chromium's base.

Copied tests highlighting existing overflow issues with V8's impl...

TimeDelta::Max() will initially be used in V8 to flag events that
never triggered in a TimedHistogram.

Also constexpr'ed a few things while I was in there, it's harmless
at worst and helps a little at best.
Ideally would constexpr all the Time*::From*() methods like in
Chromium but that has inlining implications and I don't know the
impact that could have on V8.

This creates a uniform PerformPromiseThen builtin, which performs the
operation with the same name from the spec, except that it expects the
handlers to be either undefined or callable already, since this is only
relevant for a single callsite (namely Promise.prototype.then).

Introduce a matching operator JSPerformPromiseThen into TurboFan, which
represents this operation and removes the additional checks in case of
Promise.prototype.then based on the information we can derived from the
receiver maps.

This yields a nice 20-25% improvement on Promise.prototype.then, as
illustrated by the following micro-benchmark

```js
const N = 1e7;
function inc(x) { return x + 1; }
function chain(promise) {
  return promise.then(inc).then(value => {
      if (value < N) chain(Promise.resolve(value));
    });
}
console.time('total');
chain(Promise.resolve(0));
setTimeout(console.timeEnd.bind(console, 'total'));
```

which goes from around 1230ms to 930ms with this patch.

Replace hard-coded uses of `kScratchDoubleReg`, `kScratchDoubleReg2` and
`kScratchQuadReg` with the safer `UseScratchRegisterScope`. The reason for doing
this is to be able to safely use these scratch registers inside the assembler
without having to worry about the code generator using them too.

For instance, using this scope showed us that `TryInlineTruncateDoubleToI` is
using a FP scratch register while the caller, the `DoubleToI` stub, is using it
too. We are safe only because the stub passes the scratch register to
`TryInlineTruncateDoubleToI` as an input. Using the scope forces us to
explicitely use the input register instead of acquiring a new scratch.
