[cfe] Add measurement for patterns This CL adds an initial framework for testing performance of programming patterns. Included is a test of the pattern used to choose implementation based on a runtime type, using either an if-then-else sequence, dynamic dispatch on the runtime object, or visitor pattern. The test framework runs the patterns on a range of inputs using a predefined set of scenarios and outputs a table of the measurements which can be copied into Google Sheets to visualize the results. Further work is to use statistics to quantify the results, and expand the framework to be used to detect asymptotic performance of algorithms used in the compiler itself.

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.
