asiva@google.com 3f14a14ee7 Implement 'dart:typeddata' directly in the VM instead of using 'dart:scalarlist' 
Review URL: https://codereview.chromium.org//12544015

git-svn-id: https://dart.googlecode.com/svn/branches/bleeding_edge/dart@19656 260f80e4-7a28-3924-810f-c04153c831b5

regis@google.com f644ba9791 Complete implementation of bounds checking in the vm, by introducing a vm object 
BoundedType that represents a type that could not be checked against an upper
bound at compile time. A BoundedType is verified at run time when used,
typically when it (and/or its bound) gets instantiated.
This fixes issues 7075 and 7625.
Added one test.

fschneider@google.com 7ea9189805 Fix null-termination bug in Stacktrace::ToCString. 
Under certain conditions Stacktrace::ToCString can return
a not null-terminated string.

This is the case when ToCStringInternal is invoked with a stacktrace
of length 0.

asiva@google.com 48418a75f7 Fix stack frame index numbers for full stack traces 
It used to be:
#0      getCurrentStackTrace (file:///tmp/junk.dart:3:5)
#0      func1 (file:///tmp/junk.dart:10:29)
#1      func2 (file:///tmp/junk.dart:14:8)
#2      func3 (file:///tmp/junk.dart:18:8)
#3      func4 (file:///tmp/junk.dart:22:8)
#4      main (file:///tmp/junk.dart:26:8)
(Notice the two #0 frames on top).

Now it will print this as:
#0      getCurrentStackTrace (file:///tmp/junk.dart:3:5)
#1      func1 (file:///tmp/junk.dart:10:29)
#2      func2 (file:///tmp/junk.dart:14:8)

vegorov@google.com baa0347253 Reapply r18377 it was reverted due to the unrelated bug it surfaced. 
Remove SminessPropagator and FlowGraphTypePropagator and all associated infrastructure and fields.

Replace multiple fields (result_cid_, propagated_cid_, propagated_type_, reaching_cid_) with a single field of type CompileType which represents an element of type analysis lattice and incorporates information about: value's nullability, concrete class id and abstract super type. This ensures that propagated cid and type are always in sync and complement each other

Implement a new FlowGraphPropagator that propagates types over the CompileType-lattice.

asiva@google.com c64871d699 First set of changes towards cleaning up the bytearray access APIs 
- Added unimplemented versions of Dart_ByteArrayAcquireData and
  Dart_ByteArrayReleaseData
- Added infrastructure to prevent callbacks into an API function that
  allocates a new object on the Dart heap or invokes dart code.
- Removed the old Dart_ByteArrayGet* access functions as it was felt that
  they have become redundant once we provide direct access to the internal
  data pointers.
- Removed DARTSCOPE_NOCHECKS as it seems to be redundant after the change
  to not create explicit stack zones on each Dart API call.

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).

in the VM isolate heap.

fschneider@google.com 3e94e4a2fa Fix bug in optimization in the presence of externalized strings. 
The class-id of string objects can be changed via the Dart API. The optimizer
has to disable hoisting class-id checks across calls. For now, loop-invariant
code motion is disabled for checks of string class-ids.
