Super initializer calls get implicitly moved to the end of the initializer list, so we don't need the two-phase constructor protocol anymore.
Ryan, can you please look at the mirror changes and check wether I've missed something?

Three types of fixes:
1. Remove redundant const_cast
2. Remove const_cast by adding const when appropiate.
3. Remove const_cast by removing const (e.g. places where we call free with it)
For now I only fixed places where the fix is local enough - i.e. does not require
changed a large amount of code.

Each script has an associated top-level class in which the top-level functions and fields are stored, and the reference to the script. All other fields in the TL class are unused. There are 380 TL classes in corelib alone; eliminating them saves space.
This CL eliminates all TL classes but one per library. All TL functions and fields in the library are stored in that TL class. Because scripts are not stored directly in functions and fields, but are accessible via their owner class, the owner of TL entities are now PatchClasses, rather than classes.

fields in a thread (i.e fields that are not Dart VM related)
- Split the Thread structure to be a pure Dart per thread structure and add
a pointer to os_thread which points to the OSThread structure
- Change Schedule/UnSchedule to set the Dart Thread structure as the TLS of
the thread when it is inside the Dart world and reset the TLS back to the
OSThread strcuture when is exits the Dart World.
- Moved the stack_base and few stack size related functions to OSThread from Isolate

A TimelineTask represents an asynchronous track of operations on the timeline.
The old API allowed multiple isolates to emit events simultaneously on the same task or to start / finish events in any order. This isn't supported by our UI and probably many other tools that consume trace-event.
With this change, operations within a TimelineTask must complete in the reverse order of their start calls (aka a stack). You can pass a TimelineTask from one isolate to another but you must first complete all open operations before passing it.
Example:
var task = new TimelineTask();
task.start('Some phase');
await someFuture;
task.finish();
Also: Add support for instant events.

- Provide a new callback to Dart_Initialize that will be called when the service isolate needs the Observatory assets
- Move asset management code out of embedder and into common dart:_vmservice
- Use the tar format as the archive format
- Add build script to generate .cc file containing the archive
- Add a simple tar parser to service isolate
This makes it possible for embedders to not bake Observatory into their executable but instead load it off disk or over the network. The standalone embedder still links Observatory into the executable.

- Blocks are associated with threads and not isolates.
- Fix isolate filters when iterating over blocks and events.
- Always add the isolateNumber argument when serializing events.
- Add new (kSerializedJSON) EventType for events already serialized to JSON.
- Have events coming from Dart code use the standard event structure w/ type = kSerializedJSON.
- Remove now unused DartTimelineEvent and machinary.
- Dart and C++ events now use the same structures and system.
