We'll let the bytecode compiler and optimizing compilers deal with dead code, rather than the ast visitors. The problem is that the visitors previously disagreed upon what was dead. That's bad if necessary visitors omit parts of the code that the bytecode generator will actually visit. I did consider removing the AST nodes immediately in the parser, but that adds overhead and actually broke code coverage. Since dead code shouldn't be shipped to the browser anyway (and we can still omit it later in the bytecode generator), I opted for keeping the nodes instead.

When an error occurs when storing the properties we either need to throw or ignore the error depending on the language mode. We used to infer the language mode from the type feedback vector.

Port c142e0a2 Original Commit Message: 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.

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.
