regis@google.com fb6d24945f Introduce class TypeRef in the VM to fully support recursive types. 
Fix issues 15244, 15148, 14869, 14000, and 13688 (was closed, but fragile).

Note that the current solution is not final as it may not be correct in more
complex cases not yet covered by language tests.
The final solution will require a 'trail' instead of a simple mark bit to
prevent operations involving recursive types to diverge.

johnmccutchan@google.com 29c01044bc This is the final breaking change in dart:typed_data needed for Dart 1.0. We need this change because the ECMAScript SIMD specification only includes Int32x4 and Int32x4List and our types must match.

- implicitly store a full stack trace in Error objects when they are thrown.
- the shlFromInt on Mints and Bigints was trying to allocate a new OutOfMemory
  exception objects instead of using the pre-allocated exception object.
  Made the implementation of these methods native so that they can use the
  pre-allocated object.
- Ensure that it is not possible to allocate new OutOfMemory or StackOverflow

hausner@google.com ed2e198b99 Mixins with Generics 
This change adds support for generics to mixins. It's not a particularly elegant
implementation, so I expect to change how it works internally in later checkins.

Also, there is still one aspect of the implementation that is incorrect. In the
case of typedef, the newly introduced name is not yet an alias for  the
mixin application. Instead, the MA is a superclass of the typedef name. That
will need to be fixed in a later checkin. I don't want to make this change
bigger.

ager@google.com 6e945a2578 Optimize the message queue for many active ports with few messages. 
The current message queue implementation is very inefficient if you are using
many active ports with few messages. This happens when you use 'call' a lot
on ports which is currently done in dart:io.

This patch does not remove messages from the queue when closing a port. Instead
it drops messages for closed ports when it processes them. This dramatically
speeds up dart:io benchmarks that enqueue tons of writes on a file output
stream.

tball@google.com 3282ae3f72 Second version of support for specifying an unhandled exception callback 
in Dart.  Isolate.spawnFunction optionally takes a callback parameter,
which is not resolved until an unhandled exception occurs.  If a callback
wasn't specified, the VM will then call an "_unhandledExceptionCallback"
function if it is defined in the isolate's source file. If no callback
is provided, the error is logged as the isolate is closed.

asiva@google.com ebbb7c4134 - Represent strings internally in UTF-16 format, this makes it 
compatible with webkit and will allow for easy externalization of
  strings. One byte strings are retained for pure ASCII strings.
  (The language specification was changed recently to reflect this as
   follows "A string is a sequence of UTF-16 code units").
- Remove four byte string class and all references to it.
- Rename some of the string functions in Dart API to make them
  consistent and better describe the underlying functionality
