[vm/aot/tfa] Build cache of dispatch targets in TFA instead of using ClosedWorldClassHierarchy from CFE Previously, TFA used ClosedWorldClassHierarchy from CFE to look for dispatch targets of invocations, and cached those lookups. However, doing lookups via ClosedWorldClassHierarchy for the first time is still slow. Now TFA builds maps of dispatch targets from AST and no longer uses ClosedWorldClassHierarchy for the lookup. Improves time of AOT compilation step 2 (TFA) on a large Flutter application 170s -> 152s (-10.5%).

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.
