Flow analysis: remove redundant assertion from constructor.

The assertion in the `_FlowAnalysisImpl` constructor was unnecessary
because it was checking that all variables that are reported to
`AssignedVariables` as read or written must also be reported as
declared. This is already checked by assertions in
`AssignedVariables.finish`, which is called by the `_FlowAnalysisImpl`
constructor.

I've added tests to `assigned_variables_test.dart` to confirm that
these assertions work, and I've also cleaned up the assertions a bit,
eliminating some redundancy and ensuring that in the event of a
failure the assertion failure message will be comprehensible.

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).
