Schedule is simpler compared to the schedule in blink since it now returns deadlines based on marked bytes instead of time. If marking is ahead of schedule, return the minimum step size. Otherwise, set step size to catch up to schedule (ignoring the time passed while performing the step). No more default initial step size (needed in blink since marking speed was unknown). If estimated schedule is exceeded (marking takes longer than 500ms), the steps will try to mark all remaining objects but would still be capped by the maximum step duration of 2ms.

Starting marking required Creating a Marker and calling StartMarking. StartMarking should always have been called immediately after creating the marker. Since markers are not persisted between GC (a marker exists only while marking is in progress), it makes sense to start marking implicitly when a marker is created. Calling StartMarking in MarkerBase ctor is inadvisable since subclasses might still to initialize fields. Using MarkerFactory instead guarantees that StartMarking is always called immediately after creating a Marker.

In certain situations (especially if the profiler is disabled) it can happen that multiple isolates trigger tier-up at the same time. Each recompilation would then identify the set of functions to recompile and add compilation units for them. This creates lots of redundant compilation, which takes time and can exceed the total wasm code space limit (code would later get garbage-collected, but there is a high peak). This CL fixes that by always finishing a running recompilation before starting a new one. Since typically concurrent recompilations all recompile for the same tier, this would avoid do most compilation only once, and later recompilations can skip most functions. The only redundant compilation that can happen is via compilation units that are still executing while the next recompilation starts, but those should not create too much redundant code.

In order to improve our tiering strategy, it is a good idea to start by tiering up functions that will be used the most, as this is done in most JavaScript engines. To decide which function requires tiering, we use as a basic strategy to define its compilation priority to 'func_size * number_of_calls', this roughly approximates the time we spend in the function. To handle prioritization, it seemed that using a concurrent priority queue similar to BigUnits was causing concurrencies issues. I then decided to use different priority queues for each worker thread.

The {priority_} field is being updated in {DefaultJobState::Join}, under {mutex_}. In other places though, it is read unprotected (without holding the mutex), leading to data races. This CL fixes that by reading the field while holding the mutex and using the read priority after releasing the mutex. Note that the {priority_} field is documented to be protected by {mutex_}, so the unprotected read was a bug.

The fuzzers were calling the compiled function without passing explicit arguments. Thus all arguments were converted from the "undefined" value, which typically results in a zero value, as expected. For BigInt though, it's not allowed to pass "undefined". We have to pass a proper BigInt. This CL implements this by passing explicit parameter values for all parameters. This effectively unlocks testing BigInt parameters in all fuzzers, thus may increase coverage and find new bugs.

Partially TNodify the method just to get ParameterMode out of the way. There is more TNodification needed but method is complicated and we are now focusing on removing ParameterMode entirely.

This CL unifies both map-processor and ic-processor's map processing pipeline to the same format. Also, adds the functionality to search for map transitions on map panel by clicking on map property of the ic-panel.

When we used the tasks API, we distributed the compilation deadlines such that different tasks would finish (and publish) at slightly different times. When moving to the jobs API, this feature was lost, and all tasks now only publish once all compilation is done. This creates major contention and synchronization overhead after compilation, which can take roughly as long as the actual concurrent compilation. This CL reintroduces a mechanism for ensuring regular publishing. We choose a limit which is high enough to ensure that we don't publish too often (because that comes with overhead), but low enough to ensure that not too many units are published at the end, when all compilation is done. At that point, there will still be some contention. Also, choose a slightly different limit per task to ensure proper distribution of publishing over time (different tasks are likely to publish at different times). This removes the last remaining regressions when compiling big modules via the jobs API. In local measurements, it makes us even faster than with the tasks API.
