This is a simple string-based intermediate representation for Dart
code, similar to kernel but with a far simpler structure and a compact
string encoding, suitable for use in unit tests.
I've integrated this representation into mini_ast.dart in a
preliminary way, so it is created as a by-product of running flow
analysis tests. But as yet there are no tests that validate the
correctness of the result. I plan to refine the representation, and
test it fully, in follow-up CLs.
