Teagan Strickland 2e197ae4de [vm/compiler] Tweaks and additions to IL serializer/S-expressions. 
* Add a new `SExpDouble` atom and change `SExpNumber` to `SExpInteger`.

* Allow for negative integers in deserialization.

* Add support for `LocalVariable`s and related instructions.

* Function objects are now represented by actual S-expressions generated
  with the new `FunctionToSExp` method. Previously, they were only represented
  by a symbol containing their canonical name.

* The top-level tag for a serialized flow graph is now `FlowGraph`, not
  `function`. This avoids confusion between serialized flow graphs and
  serialized function references. Similarly, the old `FunctionToSExp`
  method is now called `FlowGraphToSExp`.

* Made all SExpression* returning functions that take Object (or subclass)
  instances return nullptr if the passed in instance is the null object,
  except for ObjectToSExp, which returns the symbol `null`.

* Factored out creating tags for the different kind of block/function
  entry and also created an `Entries` section to the top-level `FlowGraph`
  form that contains function entry points similar to the `Constants` one
  instead of inlining entries as separate elements in the `FlowGraph` form.

* Additional extra information in verbose mode for some elements.

Dart

A client-optimized language for fast apps on any platform

Dart is:

  • Optimized for UI: Develop with a programming language specialized around the needs of user interface creation

  • Productive: Make changes iteratively: use hot reload to see the result instantly in your running app

  • Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web

Dart has flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:

  • Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.

  • Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
