This increases our "local" coverage of the constant evaluator. Run with something like `pkg/front_end/test/fasta/strong_tester.dart -DupdateExpectations=true -DstressConstantEvaluator=true -DskipVm=true` there is now almost coverage of everything (or a comment in the code suggests that the path is probably unreachable). Note that `out/ReleaseX64/dart pkg/front_end/test/vm_service_coverage_constant_evaluator.dart pkg/front_end/test/fasta/strong_tester.dart -DupdateExpectations=true -DstressConstantEvaluator=true -DskipVm=true` has erroneous misses, for instance (but not limited to) asserts. These are caused by errors in the VM. A follow-up CL will be created to turn on "stressConstantEvaluator" by default and print out any sucesses in the expect files.

Dart Kernel
Dart Kernel is a small high-level language derived from Dart. It is designed for use as an intermediate format for whole-program analysis and transformations, and to be consumed by codegen and execution backends.
The kernel language has an in-memory representation in Dart and can be serialized as binary or text.
Both the kernel language and its implementations are unstable and are under development.
This package contains the Dart part of the implementation and contains:
- A transformable IR for the kernel language
- Serialization of kernel code
Note: The APIs in this package are in an early state; developers should be careful about depending on this package. In particular, there is no semver contract for release versions of this package. Please depend directly on individual versions.
See ast.dart for the in-memory IR, or binary.md for a description of the binary format. For now, the textual format is very ad-hoc and cannot be parsed back in.
