dartk and other command-line tools no longer rely on analyzer classes
like AnalysisContext or DartSdk, and instead use only the interface
defined in loader.dart.
The class AnalyzerLoader has been renamed to DartLoader.
The sharing of state in batch mode is now owned by loader.dart, so
dartk.dart does not deal with DartSdk and package_config.
Repository no longer has a package or SDK path. These concepts are
now specific to the Dart frontend. Consequently, loading a binary
file no longer relies on URI resolution.
The Repository class is now more clearly focused on linking symbolic
names to their IR objects, which for the time being is only
URI-to-library bindings, but should be extended to support linking
class and member references across different files and different
loaders.

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.
