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.
