Before: Canonical names contained pointers to the corresponding Kernel
tree which assumed that the whole tree was in memory whenever the
canonical names were.
Now: Canonical names do not contain these pointers. They were only
really used to perform name-based lookup in the VM's heap so the
canonical name itself is enough.
If we later find that we need to get from a canonical name to its
Kernel tree we can add an offset in the binary (for instance) to the
canonical name or in a separate mapping on the side.

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.

This introduces
- a list of valid token positions, so debugging actually
starts to work, and the observatory can be loaded without crash.
- a list of valid yield positions, so stepping over await stuff
works as expected.
- Adding "DebugStepCheckInstr" to the kernel generated il so stepping
over await stuff works as expected, we can break in empty methods etc.
With this, approximately 80% of the service tests pass in kernel mode.

- The flow graph builder is only used to visit Statements and
Expressions so it does not need TreeVisitor as a base class. This
will make refactoring it easier.
- The TranslationHelper is bound to a Thread so we do not need
Thread::Current where we have a TranslationHelper.
- BlockExpression does not exist in Kernel any more, so it can be
removed from the C++ AST implementation.
