The new class becomes a superclass of CoreTypes, which now gets its
functionality from that class, but also exposes commonly used built-in
members as fields.
This replaces a couple of ad-hoc linear searches spread throughout
the code.
The canonical names are not a convenient interface for transformers, so
the idea is that they can use LibraryIndex to address their own runtime
libraries.
To avoid name clashes and still have a somewhat convenient interface,
getters and setters are prefixed by 'get:' and 'set:' in the lookup
table (and only in the lookup table), and top-level members can be
accessed using '::' as the class name. This is the same convention
used by the VM, although it is currently not required to be the same.

This adds a class CanonicalName that can represent a library, class,
or member. All references now go through a Reference object, which is
linked to both the AST node and its CanonicalName, so either can be
created first.
dartk now accepts multiple input files:
- If multiple dart files are given, they are all compiled.
- If multiple binaries are given, they are linked together.
Mixed dart and binary input is not supported by dartk.
dartk now has a flag --include-sdk which includes the entire SDK in
the output. This is so the SDK can be compiled alone and then linked.
Example of compiling separately and then linking:
dartk foo.dart -o foo.dill
dartk main.dart -o main.dill
dartk --include-sdk -o sdk.dill
dartk main.dill foo.dill sdk.dill --target=vm --link -o program.dill
dartk still has incredibly slow cold start due to the analyzer loading
the dart sdk, so this does not actually speed things up at the moment.

- Use strong-mode types for more precise tree shaking.
- Bail out nicely if dart:mirrors is used.
- Run the tree shaker in the VM target.
The initial tree-shaking pass could be combined with the type checking
pass (inserting implicit down casts) but for now they remain separate.

FunctionType now has a List<NamedType> which must be sorted by name.
Previously, named parameters were stored in a Map<String, DartType>.
FunctionNode still has a List<VariableDeclaration>, but this list must
now be sorted by name.

Type annotations in the supertype clauses of a class are now Supertypes
instead of InterfaceTypes. In the current version, the two classes
contain the same information, but they are about to diverge in the
following ways:
- An InterfaceType may be nullable, whereas a supertype cannot.
- An InterfaceType may represent the exact class, a subclass, or
a subtype of the given class.
- The type arguments to an interface type represent bounds, whereas
the arguments to a supertype are always exact.
We also introduce a class Substitution that represents an operator
that replaces type parameters with types, depending on the variance
of their use site.
A substitution can be applied to a DartType or a Supertype, and can
be generated independently of how it will be applied.
