This CL adds a new method to the `console` that is available when DevTools is open. In TypeScript notation the API is: ``` namespace console { // Creates a new `Task` and associates the current async // stack trace with the created `Task`. scheduleTask(name: string): Task; } interface Task { // Executes an arbitrary payload and forwards the return value // back to the caller. Any async stack trace captured during // 'f' has the site of the corresponding `scheduleTask` as // its parent. run<T>(f: () => T): T; } ``` The API is a saner user-facing API for our async stack trace mechanism: * scheduleAsyncTask corresponds to scheduleTask * startAsyncTask/stopAsyncTask are called implicitly before `f` is executed. * cancelAsyncTask is called implicitly when `Task` is GC'ed The API is behind the flag --experimental-async-stack-tagging-api Bug: chromium:1334585 Change-Id: Ic6054279a108756caed6b4b5f2d1fe4a1bdbaf78 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3776678Reviewed-by:Jaroslav Sevcik <jarin@chromium.org> Reviewed-by:

All ETW Events are controlled by v8_enable_system_instrumentation. This flag is turned off when perfetto is enabled since traces events flowing through TRACE_EVENT macros can't be intercepted by Recorder. Since, stack walking Events don't use TRACE_EVENT it can be turned back on, when using perfetto. Hence, creating a separate Build Flag for emitting stack walking event until the recorder is ported.

The CpuProfile previously emitted a CpuProfileMaxSamplesCallbackTask if there was a sample where V8 could not resolve the stack. This resulted in a premature "samplebufferfull" events for the self-profiling API. Skipping over samples without a resolved stack solves this issue.

Background: In order to show custom content in the "Locals" pane in WinDbg, v8windbg replaces the getter function for a built-in debug model property named "Debugger.Models.StackFrame.LocalVariables". This is the property that the debugger fetches when determining what to display in "Locals". The new implementation of that getter, V8LocalVariables::GetValue, can either call the original getter (so that WinDbg displays the usual content for normal C++ frames) or produce a custom result (for builtins and JIT-compiled JS frames). The current problem: In new builds of WinDbg, users of v8windbg no longer see any content in the Locals pane for stack frames that correspond to builtins or JIT-compiled code. This is because of a behavior change in WinDbg: previously, attempting to get Debugger.Models.StackFrame.LocalVariables would eagerly attempt to find the symbols for the frame and return an error code if symbols were not found, but now it returns a lazy object which does not perform symbol lookup until you iterate its properties. V8LocalVariables::GetValue currently starts with an early-exit path based on checking whether the original getter succeeded, so the new lazy implementation causes us to always take that early exit. Proposed fix: Rather than relying on the return value from the original getter, which is not guaranteed to work consistently, we can base our decisions on the instruction pointer. If it points outside any module, or if it points to within a function in the module containing V8 whose name starts with "Builtins_", then we can build a custom result for the Locals pane.
