[vm/aot/tfa] Whole-program propagation of closure values This change adds propagation of closure values to TFA. For now, inferred closure values are used only when they are constant (tear-off of a static method or a constructor). Arbitrary closures can now be referenced from unrelated members via closure-id metadata. In addition, this change fixes an incorrect stack trace when an implicit closure (tear-off) was propagated and its call was inlined. Inlining interval was not recorded because of the missing source position of a call to a target method within implicit closure.

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.
