This change adds an infrastructure to "snapshot" data that is being serialized only once. This data lives in its own per-isolate zone, wrapped in a new CompilerData class. This change reduces the "serialize standard objects" on TypeScript benchmark from ~69ms to ~30ms (more than 50% improvement).

Currently, we call the MapRef::AsElementsKind method on an initial map multiple times (from JSCreateLowering::ReduceJSCreateArray). However, this does not does not play well with the heap copier/broker, which only expectes AsElementsKind to be called on initial maps. This CL makes sure we only call AsElementsKind once (on the initial map).

Shortcuts allow identifiable primary expressions to bypass all productions starting from assignment expression. We can identify them by looking at the token after the single token of which the primary expression consists. This CL adds support for 'identifier' followed by '=' as a primary LHS.

During map updating, store the pointer to new map in the raw_transitions slot of the old map that is deprecated from map transition tree. Thus, we can get the migration target directly instead of TryReplayPropertyTransitions when updating map. This can improve Speedometer2.0 Elm-TodoMVC case by ~5% on ATOM Chromebook and ~9% on big-core Ubuntu.

Benedikt Meurer authored
Change the way that the (internal) await closures store the link to the generator object by introducing a dedicated AwaitContext, which stores the generator object into the extension slot (instead of misusing a regular FunctionContext here). Also unify the allocation+initialization of these contexts in the await-related builtins (both for async functions and generators). The rationale behind this is that for (zero-cost) async stack traces, we will need to dig into these contexts and we can do better checking with a dedicated instance type there. As an additional benefit, we save one word per await context, since we just use (the otherwise unused) extension slot to remember the generator object. As yet another benefit we will never accidentally use any of these contexts in the regular scope chain lookups, meaning we can also catch bugs there. And last but not least the objects printing machinery understands these contexts now and can even print the generator object for AwaitContexts for short printing, which is really valuable for debugging.

This CL adds a bit more rigor to the handling of length properties in JSObject-derived classes that explicitly contain that property inline. This involves: - Introducing a new superclass of JSArgumentsObject called JSArgumentsObjectWithLength that is shared with other object instances that also have a fixed length property. - Adding JSArgumentsObjectWithLength to the type hierarchy in Torque, including adding fast-cases for leading the length property for all classes deriving from JSObjectWithLength. - Adding more rigor to Context and NativeContext handling in base.tq. This is useful for the map checks required to verify objects are argument object types derived from JSArgumentsObjectWithLength.

Pending phantom handle callbacks are not reliably executed if the heap shuts down. This can cause to memory leaks or other unwanted behaviour, like in wasm where the NativeModules (held in Managed objects implemented via phantom handles) unregister from the WasmEngine in the second-pass callback. This must be executed before tearing down the WasmEngine. This CL fixes this by running pending callback synchronously on heap tear down.

The Parser inserts a temporary .promise variable to hold the outer promise for async functions, but doesn't assign an actually visible name to it. This change puts the name ".promise" on it (similar to what we do for other special variables like .result), which makes it easier to debug this (for V8 developers). It's not observable to regular developers. Bug: v8:7522, v8:8015 Change-Id: I388352ad931a49102cb5afe350314337a505a150 Reviewed-on: https://chromium-review.googlesource.com/1249106Reviewed-by:
