[cfe] Remember if finalizeExports was done Before this CL, whenever a dill library builder was asked to compute the outline it would finalize its exports - even if it was already done. This is not really a problem (it mostly puts stuff into maps --- doing it again will just overwrite what's already there with the same thing again), but when having many dill library builders, and asking them to compute the outline again and again because we've added a few new ones (e.g. via kernel worker) it adds up to a lot of wasted time. This CL adds a boolean to the dill library builders to avoid re-doing this already done work. An internal benchmark via kernel worker of lots of outline calculations in worker mode with reuse and the incremental compiler (and lots of dill loaded dependencies) goes from ~149 seconds to ~143 seconds.

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 has 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.
Visit the dart.dev to learn more about the language, tools, getting started, and more.
Browse pub.dev for more packages and libraries contributed by the community and the Dart team.
If you want to build Dart yourself, here is a guide to getting the source, preparing your machine to build the SDK, and building.
There are more documents on our wiki.
The easiest way to contribute to Dart is to file issues.
You can also contribute patches, as described in Contributing.
