Replace uses of WordEqual on two tagged representation nodes with a new TaggedEqual helper, which on pointer compressed configs only compares the bottom 32-bits of the word. We no longer allow using WordEqual on anything not known to be a WordT (i.e. Node* or TNode<Object>). In the future, this may allow us to ignore the top bits of an uncompressed Smi, and have simpler decompression, though this patch is not sufficient for such a change. As a necessary drive-by, TNodify a bunch of stuff.

This replaces all typedefs that define types and not functions by the equivalent "using" declaration. This was done mostly automatically using this command: ag -l '\btypedef\b' src test | xargs -L1 \ perl -i -p0e 's/typedef ([^*;{}]+) (\w+);/using \2 = \1;/sg' Patchset 2 then adds some manual changes for typedefs for pointer types, where the regular expression did not match.

This implements the behavior discussed and specified here: https://github.com/tc39/ecma262/issues/1461 https://github.com/tc39/ecma262/pull/1470 As part of making this change, I realized that we didn't actually toggle the behavior between the optimized and unoptimized version based on the --harmony-await-optimization flag at all and just the unoptimized version by default. This patch removes the unoptimized version and uses the optimized version as the default. The other builtins that use this flag are not touched as part of this CL, they will be updated separately.

This introduces dedicated builtins - FulfillPromise, - RejectPromise, and - ResolvePromise, which perform the corresponding operations from the language specification, and removes the redundant entry points and the excessive inlining of these operations into other builtins. We also add the same logic on the C++ side, so that we don't need to go into JavaScript land when resolving/rejecting from the API. The C++ side has a complete implementation, including full support for the debugger and the current PromiseHook machinery. This is to avoid constantly crossing the boundary for those cases, and to also simplify the CSA side (and soon the TurboFan side), where we only do the fast-path and bail out to the runtime for the general handling. On top of this we introduce %_RejectPromise and %_ResolvePromise, which are entry points used by the bytecode and parser desugarings for async functions, and also used by the V8 Extras API. Thanks to this we can uniformly optimize these in TurboFan, where we have corresponding operators JSRejectPromise and JSResolvePromise, which currently just call into the builtins, but middle-term can be further optimized, i.e. to skip the "then" lookup for JSResolvePromise when we know something about the resolution. In TurboFan we can also already inline the default PromiseCapability [[Reject]] and [[Resolve]] functions, although this is not as effective as it can be right now, until we have inlining support for the Promise constructor (being worked on by petermarshall@ right now) and/or SFI based CALL_IC feedback. Overall this change is meant as a refactoring without significant performance impact anywhere; it seems to improve performance of simple async functions a bit, but otherwise is neutral.

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).

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.

A really slight change in behaviour introduced by https://github.com/tc39/proposal-async-iteration/commit/395b2e3b2f5acb62f9fae11c5e189423d4af50e6 Just swaps the order that properties are loaded from an iterator result object in the various Async-from-Sync Iterator methods. Fixes for the test262 tests have been submitted already (https://github.com/tc39/test262/pull/961).

InternalResolvePromise, InternalPromiseReject and InternalPerformPromiseThen generate quite a lot of code. This change adds 3 new TF stubs which inline calls to these builtins. These stubs are invoked rather than inlining those operations listed above directly. This is done for Async Iteration builtins, as well as Async Function builtins. Promise builtins are left as they were, and continue to inline these calls. This results in a roughly 99kb reduction in snapshot_blob.bin on an x64 release build.

- Introduce new struct AsyncGeneratorRequest, which holds information pertinent to resuming execution of an AsyncGenerator, such as the Promise associated with the async generator request. It is intended to be used as a singly linked list, and holds a pointer to the next item in te queue. - Introduce JSAsyncGeneratorObject (subclass of JSGeneratorObject), which includes several new internal fields (`queue` which contains a singly linked list of AsyncGeneratorRequest objects, and `await_input` which contains the sent value from an Await expression (This is necessary to prevent function.sent (used by yield*) from having the sent value observably overwritten during execution). - Modify SuspendGenerator to accept a set of Flags, which indicate whether the suspend is for a Yield or Await, and whether it takes place on an async generator or ES6 generator. - Introduce interpreter intrinsics and TF intrinsic lowering for accessing the await input of an async generator - Modify the JSGeneratorStore operator to understand whether or not it's suspending for a normal yield, or an AsyncGenerator Await. This ensures appropriate registers are stored. - Add versions of ResumeGeneratorTrampoline which store the input value in a different field depending on wether it's an AsyncGenerator Await resume, or an ordinary resume. Also modifies whether debug code will assert that the generator object is a JSGeneratorObject or a JSAsyncGeneratorObject depending on the resume type.

Introduce a new Object to allow GetIterator("async") to function when the iterable does not have a Symbol.asyncIterator method. This patch has been split out from https://codereview.chromium.org/2622833002/ and incorporates test cases.
