Auto merge of rust-lang#2249 - dtolnay-contrib:rustfmt3, r=oli-obk

Format tests with rustfmt (151-200 of 300)

Extracted from rust-lang#2097.

This PR is still only doing the easy cases with no comments involved.

In the next PRs after this, I'll start grouping by common comment patterns, e.g. all the cases resembling rust-lang/miri#2097 (comment) together in one PR.
