Migrate users from the old, deprecated Subject.fail* methods to the new Subject.fail* methods or, in some cases, to Subject.check.

Most of the changes in this CL were made manually.

I've tried to preserve all information (and of course behavior!), but the format and grammar of the messages does change. For example before-and-after messages, see the LSC doc.

In some of the CLs in this round (e.g., jscomp), I don't know a lot about the domain being tested, and the assertions are complex, so please let me know if my new phrasing is wrong or confusing.

Thanks again for your patience with all the Truth changes lately.
