Format tests with rustfmt (288-299 of 299)
Extracted from #2097.
I'll make a separate PR to enable checking the `tests` directory's formatting in CI. I'll need to rebase that after both this and #2254 have landed, and if any new non-rustfmt-formatted files appear in the meantime, we can include formatting those in the same PR that enables the CI.
Format tests with rustfmt (225-275 of 300)
Extracted from #2097.
These cases all involve a line comment at the end of a block that rustfmt has chosen to wrap.
```diff
- unsafe { (*ptr).set(20); } //~ ERROR does not exist in the borrow stack
+ unsafe {
+ (*ptr).set(20);
+ } //~ ERROR does not exist in the borrow stack
```
I have moved all of those comments back onto the same line as the content of the block instead, as was indicated being `@RalfJung's` preference in https://github.com/rust-lang/miri/pull/2097#discussion_r862436672.
```diff
+ unsafe {
+ (*ptr).set(20); //~ ERROR does not exist in the borrow stack
+ }
```
