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
  exception objects.

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.

ager@google.com e676e88f81 Introduce a VM-only dart:scalarlist library for byte arrays. 
Include it in the SDK so users can use it. Create a dummy
implementation and patch file for the library for dart2js so it can be
documented. Johnni, can you think of a nicer way of making
documentation generation work for a VM only library? Also, it seems that
patching kills the documentation comments and they do not show up in
the generated docs.

lrn@google.com 292da5cc48 Make int an abstract class. 
This looks deceptively simple (the only real change is in init, which
just copies the code for double, and the rest are just renaming for
consistency). It seems to work.

hausner@google.com 5692051e4e Convert double interface into abstract class 
In a future change, we can implement double in the core
library, eliminating class Double (using the patch class
feature).

cshapiro@google.com 265e2306f5 Add a weak property type to the virtual machine. 
Weak properties are key-value pairs.  The liveness of the key determines
the liveness of the value.  If the key is reachable the value is traced.
However, if the key is unreachable, the value is subject to finalization.

At present, the sole finalization action is clearing the key and value
fields.  However, it is possible to extend this to invoking callbacks or
other techniques, as well as processing values in topological order.

asiva@google.com 5fd180cdfc 1. Register canonical names for internal VM classes and get rid of the method GetSingletonClassName 
2. Create the empty_array object as a singleton in the VM isolate and remove it from the object store
3. Remove eager population of the functions_cache entry in the class. This results in a pretty impressive reduction of the initial isolate heap size:
    - on IA32 it goes from 1331k to 1071k
    - on X64 it goes from 2431k to 1911k
    - snapshot size also is reduced from 859219 bytes to 789147 bytes.
    (as a follow up change I will consider completely removing functions cache)

asiva@google.com d4d781d636 - Unify class ids and snapshot object ids list so that we don't have disparate 
and sometimes confusing values.
- Remove instance_kind_ field from RawClass.
- Rename all class id names to have a Cid suffix.
- Remove code from object.h and object_store.h which dealt with object ids
  of predefined classes for snapshots.
