* The script had stopped working due to a pair of changes in Dart.
First, building Dart no longer produces a packages directory to use
as a package-root.
Second, generated Dart files are now formatted and the formatting
code relies on invoking Dart from the Dart SDK in order to find
dartfmt. (Specifically: invoking Dart from the build directory does
not work because there is no dartfmt there, and invoking Dart via
sdk/bin/dart from the SDK repository does not work because it is a
shell script that invokes Dart from the build directory.)
* Enable the test that the generated summary code has not changed.
* Regenerate the generated summary code.
