koda@google.com c026736cff Fix race in debug assertion. 
Change order of initialization for the two-way pointers between Isolate and Thread.

This only affects the debug assertion in Isolate::mutator_thread().

koda@google.com 0e04456696 Remove fake isolate from concurrent sweeper and extend lifetime of VM threads. 
* Use real isolate in concurrent sweeper rather than shallow copy.

The only part of the isolate, other than the page being swept, used by the sweeper is the class table (via RawObject::Size), which is now safe to read concurrently (copy-on-write).

* Do not eagerly destroy a VM thread whenever it exits an isolate.

This extends the lifetime of a VM thread across entering/exiting multiple isolates. This is necessary in case an embedder callback executes during
compilation and switches/spawns isolates.

For embedder threads, since there is no API to signal "I'm done using the VM in this thread", this means we leak the (small) Thread structure.

For our own ThreadPool threads, we explicitly clean up.

turnidge@google.com 2757d6e686 Rework error handling in the service protocol and in Observatory. 
In JSON RPC, error results and regular results are distinguished structurally.  We now do this in the service protocol instead of returning a regular result with the "Error" type.

VM:

- Add PrintError method to JSONStream.  Use this to generate all errors in the service protocol.

- Fix some bugs with "limit" parameter handling.

- Change return value for heap rpcs when they find a collected/expired reference.

- Update tests.

Observatory:

- Add app.handleExceptions -- this is a widely-used exception handler that puts up a notification when there is an uncaught/unexpected exception.  Added a top-level zone catch that uses this handler, as well as explicit uses of this handler at various points in the code.  Most pages use this implicitly or explictly, except for the debugger page, which displays exceptions in the console.

[ General rule, when a function returns a Future, generally let the error pass through.  If a function does async work but doesn't return the Future, then it should handle errors explicitly by calling app.handleExceptions, etc. ]

- Fixed notifications.  They were generally broken.  Some hard-coded type names needed to be fixed, some hacks needed to be removed.

- Add a new class RpcException and a variety of subclasses which capture the error cases when making an rpc.

- Redo refresh buttons so their callbacks return Futures instead of taking a "done" closure.  Cleaner.  Allows us to move error handling outside of the callback.

- Drop ServiceError, ServiceException and the associated views.

- Redo notifications so that event and exception notifications are supported.

- No longer null out the vm when it is disconnected.

- Remove notifications when we visit the vm-connect page.  Only show the "Proceeding will lose current page" dialog when we aren't on the vm-connect page already.

- Improve error message on cpu profile page when profiling is disabled on the VM.

- Allow variables to wrap on debugger page.

- Make eval-box and eval-link tolerant of errors during rpc.  Make the errors display nicely.

- When a breakpoint is marked "not possible", make sure it disappears.  This got broken during script view refactor.

- Drop vm's errors and exceptions streams.  No longer needed.

srdjan@google.com c969e016f3 After sudying IrregExp compilation, it seems too complicated to do lazy local var descriptors for those. The amount of eagerly generated descriptors is small enough that it IMO does not warrant the additional complexity. Cleaned up, removed the flag.
