should we just enumerate the directory? instead of hard coding

I'm thinking a better way to do this would be to a Dart file that walks over all
packages in pkg/ and third_party/pkg, determines their dependencies (a la
global_compile.dart), and invokes DDC on each package in the right order, with
the right summaries.
