When a package both transformed itself and had a dev transformer (that
is, a transformer that only runs on non-public files), *and* that
package's self-transformed code was imported by another transformer, the
dependency computer could return the dev transformer in its results.

The git invocations in the snapshot-generation code became very flaky
when run in massive parallel via the new test runner. Now a snapshot
will be used if it's manually-generated, and otherwise pub will be run
from source.

As per #1283, this makes it easier to script pub, since it's now
programattically clear whether publishing went through (or, if using
--dry-run, whether validation succeeded).

If all packages depended on by an executable don't use transformers,
this will avoid loading barback entirely and instead run the VM against
the Dart files on the filesystem.

This shaves about 600ms off the load time for "pub run test" when running from
source.

When I originally wrote this code, I hadn't thought about running tests
from within the Dart repo itself, so the snapshotting logic didn't
work for that case.

I hadn't considered the case of running tests from within the Dart repo,
but now the package-loading and SDK-detection logic works in that
scenario as well.

When running from the pub repo, dart2js needs to see SDK sources that
match up with its own version. compiler_unsupported contains its own
copy of the SDK for exactly this purpose; this CL loads SDK sources from
that copy when running tests from the pub repo.

It turns out this variable already existed, with slightly different
semantics. Everything has now been updated, so "runningAsTest" means
running in a test file and "runningFromTest" means running in pub called
by a test file.

Instead of looking in the repo's third party deps, this uses the
packages installed for pub in the package cache. Archived versions of
barback and source_maps are included via Git submodules.
