This change allowing scheduling of an arbitrary number of test tasks, the count was also augmented to better stress test the system.

That patch introduces EmbedderGraph interface that embedders can use to represent C++ objects that retain or are retained by V8 JS objects. The heap snapshot generator adds nodes and edges of the EmbedderGraph to the heap snapshot, allowing arbitrarily complex retaining paths that cross V8/Embedder boundary. The new functionality is enabled only if the embedder sets the BuildEmbedderGraph callback.

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.

We still avoid the "then" lookup using the current fast-path mega-guard in the baseline case, but in TurboFan we simply constant-fold the "then" lookup in the JSCallReducer. So all further optimizations on Promise#then in TurboFan will automatically apply to Promise#catch as well.

A given JSPromise can either be in pending state, and accumulates reactions, or in settled state, where all reactions are scheduled as microtasks, and it carries a result. So we can use a single field on the JSPromise instance to hold both the result and the reactions and that field is interpreted differently depending on the status of the JSPromise.

Also refactors code so that the remaining i64 saturating conversions should be easy to add to the wasm compiler.

The FeedbackNexus classes initially were one-to-one with IC classes, but over time this got out of date.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.

In order to support i64 values on 32 bit platforms, we extend the {LiftoffRegister} class to support storing pairs of GP registers on those platforms. On 64 bit platforms, this refactoring should cause no slowdown, as the compiler can statically determine that {LiftoffRegister::is_pair()} is always false.
