Rather than only looking at the package-level dependency graph, pub will now
examine transformer files' imports to determine dependencies between
transformers. This improves both load times and cycle detection. For example, a
package using polymer transformers can now load them in two phases rather than
four, reducing the load time by about half.

In addition, this gives transformer authors more control over how parallel their
transformer graph is. With some $include/$exclude and import tweaks, most
remaining transformer dependencies can be eliminated.

Transformers that are used in the package that defines them will be loaded in
the same isolate only if they're in the same phase. Otherwise, all transformers
within a given package will be loaded in the same isolate.

A future CL will take more advantage of this by more aggressively determining
when transformers can be safely loaded in parallel.

If we're going to claim to support older versions of barback
indefinitely, we need to test that support. This will become
increasingly important as the glue code for more recent versions
becomes more and more distinct from that for older versions.

This does slow down the time it takes to run all the pub tests by
about 20%. It may be worth considering only running a subset of
barback tests against all versions when running locally.
