Erik Ernst 945978f5c0 Change code generation for dart2js to enable capturing
This CL changes the code generation for `dart2js` (and not for any other
backend) such that the variable holding the receiver of an anonymous
method invocation is declared as a normal local variable rather than
being a `Let` variable. This is needed because `dart2js` supports
capturing the former, but not the latter.

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.
