Alexander Markov fe7778291b [vm/aot/tfa] Share captured local variables among invocations 
This is a step towards detaching bodies of closures/local
functions from the enclosing functions in TFA, so closures
could be analyzed separately.

Also, this change allows TFA to accumulate types of captured local
variables among all invocations.

On a large Flutter app, this change doesn't cause noticeable compilation
time or snapshot size changes.

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).
