Prototype shared type analysis for switches and variable patterns. This change introduces the TypeAnalyzer methods analyzeConstOrLiteralPattern, analyzeExpression, analyzeInitializedVariableDeclaration, analyzeSwitchExpression, analyzeSwitchStatement, analyzeUninitializedVariableDeclaration, and analyzeVariablePattern. These are sufficient to analyze legacy switch statements and legacy variable declarations, as well as switch statements and switch expressions involving either constants or variable patterns. Although the code is not used in the analyzer or front end yet, it is unit tested in isolation, and it's integrated into the existing flow analysis unit tests. A few minor tweaks had to be made to flow analysis to support this new functionality. There should be no visible effect to existing analyzer or front end behavior.

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).
Dart is free and open source.
