[vm/aot] Two improvements to signature shaking - Global parameter use analysis: when a parameter is only used directly as arguments to other calls, only consider it used if any of the target parameters are used. - A parameter can be eliminated if the TFA infers that it has a constant value in every implementation. Reduces ARM64 .so size of Flutter Gallery by 0.25% uncompressed, 0.37% with gzip and 0.45% with brotli. TEST=Existing test suite, expectation files for TFA test.

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.
