Issue 3551
This change adds const as a valid keyword to declare fields and
variables. The mandatory initializer has to be a compile time
const expression.
Static final variables still have to be initialized with
compile time constant expressions. I will add non-const static
finals (issue 3558) in another change.
Other small changes:
- allow null in some compile time constant expressions.
- allow only numbers, booleans, strings and null in compile time
constant string interpolation.

- 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.

This profiler will write binary HPROF data to a user provided stream that
can later be viewed by tools such as the Eclipse Memory Analyzer.
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.

Removed initializations of class_ field done in runtime and generated code on ia32/x64.
Changed forwarding address encoding used by scavenger: kFreeBit is now used to distinguish evacuated objects from not evacuated because scavenger will never encounter real FreeListElement.
Changed FreeListElement layout to match RawObject layout.

- Single step now steps to a safe point on the next line.
- Step into no longer steps into library code.
- Each library has a flag that specifies whether one
can step into its code.
Later I will add an API to set the per-library flag. Currently
it's set to true for the top-level library and to false for
all other libraries.

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.

Extend x64 disassembler with ability to decode and output recorded comments.
Example output (currently comments are emitted only by flow graph compiler at block/instruction boundaries, once instruction printing is refactored and supports printing into buffer simple "instruction" comment will be replaced with the actual IL construct):

Change 6302 description:
- Wire the stack frame iterator to use stack maps for traversing objects if
there are stack maps in the code object. If there are no stack maps it still
does the old style stack frame traversal between fp and sp looking for tagged
pointers.
- Added a mechanism to be able to iterate over the code space and look for a
particular object.
