In the new variable model `this` is treate as a variable. Similarly to other variables, it is placed into a variable context, which is treated as the point of declaration of `this` variable. Since parameter lists of a `FunctionNode`, such as `FunctionNode.positionalParameters` and `FunctionNode.namedParameters`, aren't treated as declarations either, but rather as a convenient way to access the parameters, a similar treatment of `this` variable is introduced in this CL, where it becomes accessible via `FunctionNode.thisVariable`, in addition to being declared in an appropriate variable context.

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.
