[dart2js] Speed up FunctionSet.query by organizing nodes by private/public and private by URI.

All nodes that match must be visited and compared to the queried selector. By organizing private nodes by URI the scope of nodes that need to be visited us much smaller.

In a big application this reduced the runtime of phase 2 by ~20s (~180s -> ~160s).

I see no significant memory difference from this change. +.1GB RSS according to DevTools directly after FunctionSets are initialized.

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).
