Even though both are allowed in the style guide, it recommends to use 'using', as its syntax is more consistent with the rest of C++. This CL turns all typedefs in heap code to 'using' declarations.

The concurrent marker can now process all objects. This patch also eagerly visits the objects that undergo layout changes. This is because previously such objects were pushed onto the bailout worklist, which is gone now. To preserve the incremental step accounting, the patch introduces a new GC tracer scope called MC_INCREMENTAL_LAYOUT_CHANGE.

A background task can now use GCTracer::BackgroundScope to trace the time spent in the task. The time shows up in --trace-gc-nvp output and in the runtime call stats for GC. The destructor of GCTracer::BackgroundScope increments the corresponding counter in heap()->tracer()->background_counter_, which is protected by a mutex. The GCTracer::Stop function fetches background_counter_ items into the global scope and into the runtime call stats.

For the Scavenger we require a first pass over global handles for identifying unmodified nodes because the Scavenger might have already written forwarding pointers during scanning, making it hard to perform the proper checks. The minor MC does not mutate the object graph during marking and can thus merge this phase into the regular phase executed during marking roots. Furthermore, moves processing into the parallel marking phase of the minor MC collector.

In the spirit of the full MC, we evacuate and update pointers in parallel for the young generation. The collectors are connected during incremental marking when mark bits are transferred from the young generation bitmap to the old generation bitmap. The evacuation phase cannot (yet) move pages and relies completely on copying objects.

A fast promotion mode that works solely on GC heuristics without requiring compiler or other profiler support by implementing zero-copy evacuation for new space. - Once a threshold of survived bytes in the Scavenger is reached the mode is activated. - In fast promotion mode all pages are moved to old space instead of performing a Scavenge. - The inevitable upcoming full MC determines whether the decision whether the mode should stay on or be turned off based on the young generation survival rate.
