regis@google.com cd746c8172 Initial revision of ARM simulator and (empty) MIPS simulator. 
Review URL: https://codereview.chromium.org//12041056

asiva@google.com f4fe42c280 Added macros OBJECT_IMPLEMENTATION and FINAL_OBJECT_IMPLEMENTATION 
which have different implementations of 'operator=' and 'operator^='.
In the case of FINAL_OBJECT_IMPLEMENTATION we do not do the vtable setting
in these methods (Note the |= operator functionality is now subsumed into
the new implementation of "operator^=")

asiva@google.com 4c796304dd Move verification of builtin_vtables into Dart::InitializeIsolate. 
This ensures that we don't ASSERT on every handle assignment
(not an issue with release builds but should help the debug builds some).

turnidge@google.com 9d72035ce5 Use the ThreadPool for all isolates and native ports. Previously, 
each isolate or native port had a dedicated thread.

Refactored the MessageHandler api...

- Added a Run function to allow a MessageHandler to run on a
  ThreadPool.  These functions take a start and end callback to allow for
  isolate initialization and shutdown.

- Made the queue private to the MessageHandler and moved all message
  processing code inside the MessageHandler (got rid of all of the
  different flavors of RunLoop).  This helps remove some code
  duplication and hides the details of how messages are handled.

- Moved all locking and notification out of MessageQueue and moved it
  up to MessageHandler.  Moved OOB support out of MessageQueue and up
  to MessageHandler.  These changes make the MessageQueue much
  simpler.

- Refactored native port and isolate MessageHandlers to share more code.

- Improved --trace_isolates output.

- Added tests for MessageHandler.

Refactored lib/isolate code...

- Use the new MessageHandler::Run api.

- Got rid of the LongJump stuff in RunIsolate.  No longer needed.

- Use the new StartIsolateScope/SwitchIsolateScope to make the code
  less verbose and less error-prone.

- Store top-level isolate errors in the sticky_error.

Added StartIsolateScope/SwitchIsolateScope classes.

On standalone dartium which has about 50000 tokens in the libraries (core, coreimpl, builtin, io etc.) this reduces the heap size by about 180kb. The size of the standalone snapshot buffer reduces by about 72kb.

Also moved the keyword symbol table to the object store so that it does not have to repopulated on every script compilation. Should benefit regular user script load times.

Dart_CMessage structure. The Dart_CMessage structure is allocated
in a zone and the callback receiving it should expect the
lifetime to be controlled by the caller.

isolate. Changed the GrowableArray to support allocating in
aprovided zone instead of the zone for the current isolate.

turnidge@google.com 9da62c5fea Add Dart_PropagateError. 
This function can be used in native functions to properly pass all
errors up the stack.

Set the long jump base in the Compiler instead of outside of the
compiler.  A bunch of errors that used to be propagated through the
sticky_error are now propagated through return values.  This includes
all of the DartEntry and DartLibraryCall functions.

In particular, we no longer use the long jump to cross dart frames.
Instead errors are propagated across dart frames using the same
mechanism that we use for unhandled exceptions.  I've added assertions
to make sure that we only use the long jump when it is "safe".

- Store the current isolate pointer in the snapshot reader object and use it instead of calling Isolate::Current() during the deserializing process.

turnidge@google.com 0b833d4977 Add support for interrupting an isolate in the vm. Interrupts are 
implemented by extending the existing support for stack overflow
checking in the vm.  When an interrupt is scheduled for an isolate, we
overwrite the isolate's stack limit with a value guaranteed to cause a
stack overflow.

We support multiple kinds of interrupts, encoded in the low bits of
the stack limit.

Add Dart_InterruptIsolate and Dart_InterruptIsolateCallback to the
dart embedding api to allow the embedder to request and handle
interrupts.

Add EXPECT_SUBSTRING(needle, haystack) testing macro.
