Refactor the CallApiCallback builtin to - pass the context as with other stubs, and - pass holder and call data in registers. This avoids having to place holder and call data onto the stack, and thus makes it possible to easily call the CallApiCallback builtin from other builtins while just forwarding the (stack) arguments. The idea is to use this in the future to optimize the general case of calling into any API method via a FunctionTemplateInfo and doing appropriate security and/or interface checks upfront as necessary (eventually making the HandleApiCall C++ builtin obsolete at some point).

Each page has a `live_byte_count_` field in its header and it is always accessed with atomic operations. However, apart from one corner case, this field is only accessed by the main thread so let's remove the atomicity by default. To summarise, this changes the MarkingState accessors in the following way: - IncrementalMarkingState: Accesses of live_byte_count_ are now non-atomic. Concurrent marking uses local maps of live bytes per page so we have exclusive access to the field when using this. - MajorAtomicMarkingState: This accessor does not guarantee exclusive access to live_byte_count_ so we need to keep the access atomic. This is used by the scavenger when migrating an object that was marked black, since marking an object black will implicitly increment the live_byte_count_. Additionally, the live_bytes() and SetLiveBytes() accessor methods were not used so remove them. - MajorNonAtomicMarkingState: Accesses of live_byte_count_ are not actually non-atomic. - MinorNonAtomicMarkingState: The `young_generation_live_byte_count_` field is atomic so we can set the memory order manual to relax accesses.

Sets an atomic field on each sampler when it requests a sample, to be checked when the SIGPROF handler is executed. A counter is not used since signals may be coalesced. Prior to this change, all samplers attached to an isolate received samples when other samplers sent SIGPROF to the VM thread. This change alters the behaviour of different CpuProfiler instances on the same isolate to be in line with the Windows / Fuchsia behaviour.

The StackTraceFrame object will be used in a future CL to replace StackFrameInfo as the object returned by the inspector API, as well as the object used in the stack_frame_cache. The object itself is a simple wrapper around a reference to a FrameArray plus an index, as well as a reference to a StackFrameInfo object that will get lazily initialized. This is the first step towards unifying stack trace representation and collection.

This updates the type of contexts to NativeContext instead of Context, namely on GetFunctionRealm(), GetCreationContext(), and JSGlobalObject::native_context. They should be semantically NativeContexts, but the return type hides the underlying NativeContext, and causes its user to cast the context to native.

The previous change to JSCallReducer::ReduceCallApiFunction regressed the case a bit where the optimized graph has some knowledge about the receiver already, but the API callback didn't need any receiver checks, as in that case we unnecessarily added a ConvertReceiver node. This change refactors the code to first see if there's information in the graph about the receiver, and only if none is found, introduce the ConvertReceiver node. It also removes the unnecessary context load from the target function, since the API callback doesn't care about the concrete context, and we never inline cross native contexts, so using whatever incoming context we have is perfectly fine (and saves us from unnecessarily materializing the target just to load the native context off of it). Drive-by-fix: Remove bogus comment about CallApiCallbackStub parameters.

When calling API functions (i.e. Blink C++ DOM methods and accessors) directly from TurboFan we currently only optimize that to a fast call via the CallApiCallback builtin when TurboFan is able to find reliable map information about the receiver in the graph. This is usually only the case when the call is preceeded by a monomorphic or polymorphic property access on the receiver, i.e. something like ```js element.hasAttribute("bar"); ``` will work, since the call to the `hasAttribute` method is immediately preceeded by a `CheckMaps(element)` in the monomorphic/polymorphic case. However this no longer works when the responsible LOAD_IC was megamorphic or the method is called via `Function#call()` for example: ```js const hasAttribute = Element.prototype.hasAttribute; // ... hasAttribute.call(element, "bar"); ``` This change allows for more optimizations in two cases: 1. When the method accepts any receiver (i.e. no signature type and no access checks needed), and 2. when we find information about the receiver in the graph, but that information is not reliable. For the first case, when the API method accepts any receiver and doesn't limit it to specific types of receivers (aka no compatible receiver check is required), we just insert a ConvertReceiver receiver and pass the result as both the receiver and the holder to the API callback. For the second case, we lift the current restriction of only supporting reliable, stable receiver map information, because we only need to know two things: a. The Map::constructor field on the root map satisfies the compatible receiver check. b. If the receiver is a JSObject, then the "access check needed" bit is not set (or the API method accepts any receiver). Both of these cannot change with map transitions. So if at some point in the past we knew that this held for a given receiver (by looking into the TurboFan graph), we definitely know that it's still going to hold at any later point.

This CL moves MicrotasksPolicy from Isolate's HandleScopeImplementer to MicrotaskQueue for better non-default MicrotaskQueue support. After this: * MicrotaskPolicy is per-MicrotaskQueue rather than single global one. * ENTER_V8 runs MicrotaskQueue associated to the current Context, rather than the default_microtask_queue(). * SuppressMicrotaskExecutionScope and MicrotasksScope are ready to take MicrotaskQueue parameter, rather than using the default one. Note that there's no way to use a non-default microtask queue until we expose it as a V8 API.

Currently, PRIVATE_NAME / PrivateIdentifier is not valid in ObjectLiterals or other places expecting the PropertyName production. A SyntaxError here prevents an access violation later on when attempting to dereference a null property key BUG=v8:8808 R=gsathya@chromium.org, littledan@chromium.org Change-Id: Idde9c669cb48c1595b83115351a8fe0caed40eef Reviewed-on: https://chromium-review.googlesource.com/c/1461161Reviewed-by: Georg Neis <neis@chromium.org> Commit-Queue: Caitlin Potter <caitp@igalia.com> Cr-Commit-Position: refs/heads/master@{#59515}

The line number is associated with each sample along with pointer to the ProfileNode and timeDelta. Once collected line numbers are streamed as an array of integers in "ProfileChunk" trace events. If all the line numbers are zero, the array may be omitted. Otherwise the array length matches length of samples and timeDeltas arrays.
