This CL completes the migration of the first wave of
interdependent libraries in package:kernel, including ast.dart.
In order to ensure non-nullability on AST properties, the Transformer
has been split in 2 variants: Transformer which doesn't support
removal of nodes and RemovingTransformer which supports removal where
allowed by the context using 'removal sentinels'.
Start reviewing Transformer and RemovingTransformer in visitors.dart
since many of the changes are caused by the changes here.
Included in the migration are the mixin_deduplication.dart and
unreachable_code_elimination.dart since these needed porting to
the RemovingTransformer which was aided by opting in the libraries
which only depended on ast.dart.

Before a import of, say "hello.dart" was printed as
"import './hello.dart'".
Now instead it is printed as "import 'hello.dart'".
At the same time we get rid of a dependency.

This required a couple small fixes where we had made assumptions in our system
about not having anything other than dart, package, and file URIs.

We need the ability to efficiently transform a mixin application class
into a regular class, and the separation was obstructing it. It also
simplifies the IR a bit, although it no longer enforces the invariant
that mixin applications cannot contain fields and procedures.
The binary format is unchanged, so the separation still shows up in
there. This ensures the CL can land without any changes to the SDK.
