The multi-return fuzzer was able to generate more than 256 parameters of
the same type. However, the fuzzer itself could not deal with so many
parameters. With this change more than 256 parameters of the same type
can be handled and tested.

This adds a new isolate wide Promise#then protector, which guards the
"then" lookup for all JSPromise instances whose [[Prototype]] is the
initial %PromisePrototype%. Thus arbitrary mutations to the
Promise.prototype (i.e. monkey-patching other methods or installing
new functions) no longer sent you down the slow-path. Use this protector
in Promise.prototype.catch and in Promise.resolve.
Drive-by-fix: Restructure the resolve logic a bit and avoid the
expensive and large SameValue check, which can be turned into a simple
reference equal, as the promise in there is known to be a JSPromise
anyways.

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).

TimeDelta::Max() will initially be used in V8 to flag events that

Also constexpr'ed a few things while I was in there, it's harmless

Ideally would constexpr all the Time*::From*() methods like in

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.

NewPromiseCapability functionality from TurboFan optimized code
eventually.
Also remove the unused %new_promise_capability intrinsic and the builtin

It was already always high-resolution on POSIX but was never high
resolution on Windows. Windows does support low latency high-resolution
timers for the majority of our user base.
TimeTicks::HighResolutionNow() was only explicitly requested in testing
frameworks. As such I left the call in place but made it DCHECK that
it's running on a Windows machine on which high-resolution clocks are
used. This confirms that none of our test fleet has regressed with this
change (the previous HighResolutionNow() used to be slightly more
aggressive and also do it in a few configurations where we now fallback
to low-resolution now).
This implementation was copied as-is (modulo minor v8 API
compatibility tweaks). These implementations were the same in the
past but had diverged when, sadly, the same bug was fixed separately
years apart, in Chromium and V8:
chromium: https://codereview.chromium.org/1284053004 + https://codereview.chromium.org/2393953003
v8: https://codereview.chromium.org/1304873011
This is a prerequisite to add metrics around parallel task execution
(low-resolution clocks are useless at that level, but we also don't want
to incur high-latency clocks on machines that can't afford it cheaply).

Previously we would directly take the result from a fulfilled native
promise bypassing the microtask queue. This is observably different
from the spec.
Note: Our variant of the bluebird benchmark is heavily favored towards
fulfilled native promises because we don't use setTimeout (unlike the
original benchmark). I suspect this pattern doesn't appear often in
the wild so it's fine to take this hit for now.
PSA for Perf sheriffs: this is going to tank some benchmarks.

The FeedbackNexus classes initially were one-to-one with IC classes,
but over time this got out of date. We also found Nexus' useful, so
we made more classes even for cases that weren't ICs.
The inheritence and polymorphism became confusing and led to
duplication. Better, to just talk about a (single) FeedbackNexus.

The fuzzer found a couple of cases that exploited comments of the
form:
function test() {
const re = /*.../;
const str = '...*/...';
let result;
try { result = re.exec(str); } catch (e) { /* ... */ }
}
Note that the first line does not contain a regexp literal, it starts
a comment instead. The second line terminates the comment.
This fixes detection of such cases by initializing `result` to null.

This implements the ideas outlined in the section "Microtask queue"
of the exploration document "Promise and async/await performance" (at
https://goo.gl/WHRar2), except that the microtask queue stays a linear
FixedArray for now, to avoid running into trouble with the parallel
scavenger. This way we can already save a significant amount of
allocations, thereby reducing the GC frequency quite a bit.
All items on the microtask queue are now proper structs that subclass
Microtask, i.e. we also wrap JSFunction and MicrotaskCallback jobs
into structs. We also consistently remember the context for every
microtask (except for MicrotaskCallback where we don't have a
context), and execute it later in exactly that context (as required
by the spec anyways for the Promise related jobs). Particularly
interesting is the PromiseReactionJobTask and its subclasses, since
they are designed to have the same size as the PromiseReaction. When
we resolve a JSPromise we just take the existing PromiseReaction
instances and morph them into PromiseFulfillReactionJobTask or
PromiseRejectReactionJobTask (depending whether you "Fulfill" or
"Reject"). That way the JSPromise class is now only 6 words instead
of 10 words.
Also the PromiseReaction and the reaction tasks can either carry a
JSPromise (for the fast native case) or a PromiseCapability (for the
generic case), which means we don't always pay the overhead of having
to also remember the "deferred resolve" and "deferred reject" handlers
that are only relevant for the generic case anyways.
It also fixes a spec violation where we called "then" before we actually
enqueued the PromiseResolveThenableJob, which is observably wrong.
Calling it later has the advantage that it should be fairly
straight-forward now to completely avoid it for native Promise
instances.
This seems to save around 10-20% on the various Promise benchmarks and
micro-benchmarks. We expect to gain even more as we're now able to
inline various operations into TurboFan optimized code easily.

This is a reland of 76195d9e08.
It was reverted because the new parallel tasks (with higher number
of workers) hang on client.v8.ports bots. Since each test task steals
the worker thread it's assigned but only processes one item before
waiting for completion by others: I think the problem is that there
aren't enough workers in client.v8.ports' config. There aren't any
try bots for this config... reduce the tests to use 4 tasks and
hope for the best (i.e. a 4 core machine that uses "num cores")...

With the new builtin optimization guard we can just speculatively assume
that the index passed to String#charAt and String#charCodeAt (in
optimized
code) is going to be within the valid range for the receiver. This is
what Crankshaft used to do, and it avoids Smi checks on the result for
String#charCodeAt, since it can no longer return NaN.
This gives rise to further optimizations of these builtins (i.e. to
completely avoid the tagging of char codes), and by itself already
improves the regression test originally reported from 650ms to
610ms.
