Introduce a "mini IR" representation for use in _fe_analyzer_shared testing.

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.
