New intstrumentation consists of: - kAsyncFunctionSuspended when async function is suspended on await (called on each await), - kAsyncFunctionFinished when async function is finished. Old instrumentation was based on reusing async function promise. Using this promise produces couple side effects: - for any promise instrumentation we first need to check if it is special case for async function promise or not - it requires expensive reading from promise object. - we capture stack for async functions even if it does not contain awaits. - we do not properly cancel async task created for async function. New intsrumntation resolved all these problems as well as provide clear mapping between async task and generator which we can use later to fetch scope information for async functions on pause.

This refactoring makes it easier to write advanced tests and gives full control over what's happening to the test code. It also forces description for every test. BUG=none Review-Url: https://codereview.chromium.org/2891213002 Cr-Commit-Position: refs/heads/master@{#45412}

With creation frame we can show additional information with description of each async stack trace, which could help user to understand where promises were chained. At least in case of Promise.resolve().then(foo1).then(foo2) we would be able to show following stack trace for break in foo2 callback: foo2 (test.js:14:2) -- Promise.resolve (test.js:29:14)-- -- Promise.resolve (test.js:28:14)-- promiseThen (test.js:30:2) More details: https://docs.google.com/document/d/1u19N45f1gSF7M39mGsycJEK3IPyJgIXCBnWyiPeuJFE BUG=v8:5738 R=dgozman@chromium.org,gsathya@chromium.org Review-Url: https://codereview.chromium.org/2648873002 Cr-Commit-Position: refs/heads/master@{#42682}

... which were done after the promise has been resolved. Goal of this CL - change promise instrumentation to support better callbacks, chained after promise resolution and prepare instrumentation for adding new asyncTaskCreated instrumentation. Instrumentation changes: - asyncTaskScheduled(recurring) when promise is fulfilled or rejected, - asyncTaskCancelled when promise is collected (since [1] we can be sure that promise will survive scheduled microtasks). Minor changes: - async task type in inspector <-> debugger API transferred by enum instead of string, - Debug manages async task ids based on promise objects.
