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.

- This CL only adds support for synchronous blocks of time. A follow up CL will add asynchronous blocks of time.
- Reports true thread id to tracing system. This is an improvement over Mojo's tracing helper.
- Dart events are included in individual isolate traces and global traces obtained via the embedders API.
- Dart events are included in the write to disk path (--timeline_dir).

- Rename accessors of class Field to make it more apparent as to what is being accessed (static field values or instance field offsets
- Use precompiled initializer state (Used only during precompilation) to also store saved initial value of static fields (Used only during application snapshot generation)

Pass on the incoming arguments descriptor when invoking an irregexp function.
Avoiding loading an arguments descriptor in the intrinsic code also allows
generated regexp code in precompiled code.
Loading a new descriptor is not necessary since the arguments are already on
the stack in the right order.
Use named constants for parameter indices in the regexp assembler.
