This CL ensures that elements kind transitions don't cause silent mutable-to-constant or any-to-class-type migrations of in-place generalizable fields.

Sometimes we need to capture stack trace on one debugger and use it later as a parent stack on another debugger (e.g. worker.postMessage). This CL includes following addition to our protocol and v8-inspector.h: - added Runtime.StackTraceId, this id represents stack trace captured on debugger with given id, - protocol client can fetch Runtime.StackTrace by Runtime.StacKTraceId using Debugger.getStackTrace method, - externalParent field is added to Debugger.paused event, it may contain external parent stack trace, - V8Inspector::storeCurrentStackTrace captures current stack trace and returns V8StackTraceId for embedder this id can be used as argument for V8Inspector::externalAsyncTaskStarted and V8Inspector::externalAsyncTaskFinished method. Any async stack trace captured between these calls will get passed external stack trace as external parent. These methods are designed to be called on different debuggers. If async task is scheduled and started on one debugger user should continue to use asyncTask* API, - Debugger.enable methods returns unique debuggerId.

Clemens Hammacher authored
The Label class currently allows to be copied on all platforms except for arm64, where it can not be copied or moved. This allows too much though: Copying a label even on another platform than arm64 might fail if the label was linked already, because only one of the copies will be bound later, and the other will fire a DCHECK error in its destructor. This CL changes the restriction to never allow to copy construct or assign a Label, but allow move construction and move assignment on all platforms except arm64. This will allow to place Labels in containers, as will be done in Liftoff (except for arm64, where it still needs to be allocated on the heap).

Old instrumentation was designed to collect promise creation stack and promise scheduled stack together. In DevTools for last 6 months we show only creation stack for promises. We got strong support from users for new model. Now we can drop support for scheduled stacks and simplify implementation. New promise instrumentation is straightforward: - we send kDebugPromiseThen when promise is created by .then call, - we send kDebugPromiseCatch when promise is created by .catch call, - we send kDebugWillHandle before chained callback and kDebugDidHandle after chained callback, - and we send separate kDebugAsyncFunctionPromiseCreated for internal promise inside async await function. Advantages: - we reduce amount of captured stacks (we do not capture stack for promise that constructed not by .then or .catch), - we can consider async task related to .then and .catch as one shot since chained callback is executed once, - on V8 side we can implement required instrumentation using only promise hooks, Disadvantage: - see await-promise test, sometimes scheduled stack was useful since we add catch handler in native code, Implementation details: - on kInit promise hook we need to figure out why promise was created. We analyze builtin functions until first user defined function on current stack. If there is kAsyncFunctionPromiseCreate function then we send kDebugAsyncFunctionPromiseCreated event. If there is kPromiseThen or kPromiseCatch then only if this function is bottom builtin function we send corresponded event to inspector. We need it because Promise.all internally calls .then and in this case we have Promise.all and Promise.then on stack at the same time and we do not need to report this internally created promise to inspector.

Filtering by status file split to four parts: 1. Getting outcomes - reads both variant dependent and independent outcomes, no more need to do it twice. 2. Checking unused rules - has a switch to check only variant dependent/independent rules. 3. Reading flags - if outcome starts with '--' it is treated as a flag. 4. Actual filtering. Outcomes removed from the testcase object, can be accessed by call to its testsuite.
