We have many tests that explicitly use --optimization-counter-threshold= flag. We also have a CI builder that uses this flag for all tests. This is an issue for cases where `kernel-isolate` is not AppJIT'ed, which is the case for simulators and ia32. Especially in debug builds this causes a very-very slow time-to main due to JIT'ing the CFE code in `kernel-isolate` and running flow graph checker etc (in debug mode). This causes various tests to sporadically hit the timeout limit, become flaky and require gardening attention. As workarounds: the actual threshold was modified in tests, status files were updated to mark tests as Pass,Slow etc. => This Cl will make `kernel-isolate` no longer be affected by the `--optimization-counter-threshold` => This should make the cycle times faster on those modes and avoid flaky timeouts that gardeners constantly have to pay attention to.

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).
