For the --async-stack-traces we can also look through initial parts of the promise chain that were created by regular Promise#then() calls to walk up to the first async function frame. This addresses the missing support for aforementioned example ```js (async function() { await Promise.resolve().then(() => console.log(new Error().stack)); })(); ``` which now also works.

When trying to print the scope information for the class fields initializer function, the debugger asks the parser to parse the class literal as a function literal (to get the scope info) ... which doesn't quite work. Instead of adding support for parsing the class literal, we just short cicruit this parsing step by just returning an empty context. This works fine because initializer function doesn't have any variables in it's local scope. The one caveat is that the objects in the scope above this function (like the global) are now missing. This trade off is possibly fine for now, as adding parsing support for class literal to only produce would be a lot of code for not enough use. As a follow up to this change, the devtools UI needs to be updated to handle this empty context cleanly. Currently, it doesn't show the `this` object if no context exists even if the `this` object is correctly passed to the UI from the backend.

There was a small race where an idle task could be posted after the compiler dispatcher had aborted and the CancellableTaskRunner had been cancelled. This was causing flakyness on the bots. This fixes this by moving the idle task posting into the same lock block as the notification to the main thread that the background task has completed.

The bug was that I didn't emit the check if dealing with a SMI array. However, the GC subsystem at that point doesn't distinguish between SMI and OBJECT FixedArrays. This fix brings the CSA code in line with that.

The register allocator has an optimization that makes it try reuse spill-slots between phi-inputs and assign the same spill slot to a phi output, if possible. Furthermore, if the phi has no immediate register use, the output is kept spilled. With this change, no longer require that a phi input was spilled in an immediate predecessor. Instead, it is good enough if it was spilled at definition.

Adds support for enqueuing parallel parse / compile tasks for eagerly compiled IIFEs during parsing. If the --parallel-compile-tasks flag is enabled, the parser will pre-parse eager top-level IIFEs and enqueue a task on the compiler dispatcher to do the actual parsing / compilation on a worker thread. Currently we always enqueue the task, but we likely want to only enqueue parallel tasks where the script has multiple IIFEs or a substantial amount of top-level script code before the IIFE to avoid the main thread having to immediately block on the parallel task. This work will be done as a follow-up. BUG=v8:8041 Change-Id: If68d7c374548cabd4ec32f1fb6752da7d6aaae6b Reviewed-on: https://chromium-review.googlesource.com/c/1275354Reviewed-by:

Change the way we start collecting async stack traces by storing the current microtask as a root instead of trying to make sense of the last frame we see. This makes it possible to use the zero cost async stack traces in Node.js as well (where the last JavaScript frame we see is not the actual async function, but some frame related to the main event loop usually). In addition to the benefit that it now works with Node.js, we can also extend the new machinery to look through (almost arbitrary) promise chains. For example this code snippet ```js (async function() { await Promise.resolve().then(() => console.log(new Error().stack)); })(); ``` can be made to also show the async function frame, even though at the point where the stack trace is collected we don't have any async function on the stack. But instead there's a PromiseReactionJobTask as "current microtask", and we can dig into the chained promise to see where the async execution is going to continue and eventually find the await promise in the chain. This also removes the removes the need to allocate `.generator_object` specially during scope resolution.

On ia32, we were pinning too many registers, resulting in no unpinned byte registers left (we only have three byte registers since {ebx} is reserved for the root register). It turns out that on most paths, we don't actually need to pin any registers, since {Store} is often the last call for an operation (like any store or set_global). If registers need to be pinned, only pass those that must be kept alive across the {Store}. This allows to compute a more narrow set of pinned registers on demand inside {Store}. Plus minor drive-by changes.

Port a63987a4 Original Commit Message: This JSAsyncFunctionObject represents the implicit generator object inside of async functions, and also holds the outer promise for the async functions. This in turn allows us to get rid of the .promise in the Parser / BytecodeGenerator completely, and will make it possible to build zero-cost async stack traces independent of the concrete synchronous part of the stack frame (which currently breaks in Node.js). In the bytecode all the async function operations now take this new JSAsyncFunctionObject instead of passing both the .generator_object and the .promise, which further simplifies and shrinks the bytecode. It also reduces the size of async function frames, potentially making the suspend/resume cheaper. This also changes `await` to use intrinsics instead of calling to special JSFunctions on the native context, and thus reduces the size of the native contexts. to TurboFan.
