Add an AST-to-IR conversion stage to the Wolf analysis prototype.

This CL continues pulling a steel thread through the design of Wolf
analysis, by adding a stage that converts from analyzer ASTs to the
Wolf analysis IR. The set of supported instructions is still quite
minimal, so pretty much the only functions that can be handled take
the form `functionName() => literalValue;`. I plan to start adding
more instructions next.

A simple IR interpreter is included, solely for use in unit tests, so
that in the unit tests for AST-to-IR conversion, we can actually
verify that the IR properly reflects the intended semantics.

Includes a minor bug fix to the validator and improved validator
testing.

Also, a README.md file is added, giving an overview of the design of
Wolf analysis and noting that the code as currently experimental.

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's 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).
