asiva@google.com 73bfbc5da4 Allow implicit 'close your eyes' of native methods. This will hopefully fix issue 3466.
- when resolving the native method which has been closurized account for the 'this' argument in the count of arguments.
- explicitly copy the 'this' parameter in the closure context as the first parameter before calling the native function. This is done by piggy backing on the CopyParameters code used for functions with optional parameters.

While all user defined types are accurately described in the profile data,
internal types that are not self-describing appear as empty objects.  This
will be addressed by a future change.

turnidge@google.com 6a8c82db83 Implement spawnUri from dart:isolate. This function allows us to
launch an isolate running a different script.  Finally.

Reviewers: This isn't as hard to review as it looks.  Dive right in!

Siggi: Take a look at my test status file changes and make sure I'm
excluding the right stuff.

Much of the churn in the CL comes from moving ownership of the
import_map.  It used to be set per-library and is now set per-isolate.
This caused a lot of superficial diffs.

DART EMBEDDING API CHANGES:

- Dart_IsolateCreateCallback now takes a script_uri and main argument
  instead of a name_prefix argument.  The script_uri argument allows
  the callback to launch different scripts.  The main argument is used
  in creating the isolate debug name.

- Dart_CreateIsolate now takes script_uri and main arguments.  These
  are used to build the isolate's debug name.

- Dart_LibraryTagHandler, Dart_LoadScript, and Dart_LoadLibrary no
  longer take an import_map.

- Added Dart_SetImportMap.

- Added Dart_RootLibrary to provide access to the root library for the
  current isolate.

OTHER STUFF

Add a couple of tests for spawnUri -- the existing tests assume that
scripts end in a .js suffix which isn't going to work out for us.

Changed how the debug name for isolates get built a bit.

Refactored bin/main.cc a bit.  Fixed some problems with error handling
while creating isolates.

Minor refactoring in builtin.dart to always pass is_windows rather
than relying on it being squirreled away.

cshapiro@google.com 537010ea16 Implement {Int,Uint}{8,16,32,64} and Float{32,64} typed arrays.
Internal and external representations of each array are provided.  A
single interface type implementing the ByteArray and List interfaces
is shared among the internal and external implementation type.
