Error.

Sole test failure is an unrelated known flaky with a fix pending.

/ping @nodejs/ctc This is ready to land except that it needs another signoff from a CTC member because it is semver-major because of the change to the error message.

Can use a more descriptive commit title? I wouldn't know what this is about if it were in the changelog like it is.

I'm open to suggestions that are less than 50 characters. :-D

It's fine if this has to wait for Node 9.0.0 to be released, but for the record, it is the tiniest of semver majors (change in type from Error to TypeError) and I wouldn't oppose it landing in Node 8.0.0 if it's not too late. Either way is fine with me. /cc @jasnell
