Update to test package, make test work on dart2js.

Update to test package, make test work on dart2js.

The equality test was missing the status file that marked it as failing on
dart2js. Rewrote it to not compare doubles to integers and expect them to not
be identical.

Are these "status-file" comments leftovers, or should the .status file be
updated as well?

They were basically left-overs because the status file was not brought into the
package repository when it was moved out of the sdk.
