Dummy PR to test coverage test changes in CI

[Zalathar]

I have some changes to the coverage tests (#112300) that need to be tested on other platforms to make sure they don't break anything.

r? @ghost

[Zalathar]

As I suspected, uses_crate.rs and uses_inline_crate.rs actually work fine on Windows and Mac.

The run-make tests couldn't express this restriction, but with run-coverage I can just add an ignore-linux directive to those files and have them run in CI again.

New experiment: I've been assuming that uses_crate.rs and uses_inline_crate.rs still fail on Linux, but I want to verify whether that's actually still true.

[Zalathar]

Unexpectedly, those tests now seem to pass on Linux as well: https://github.com/rust-lang/rust/actions/runs/5275751902/jobs/9541593530?pr=112514

[Zalathar]

Next experiment: Check whether uses_crate.rs and uses_inline_crate.rs pass or fail on Linux on master.

This will tell me whether the failure has been magically fixed by someone else, or whether it has been magically fixed by my migration.

[Zalathar]

For reference, I last saw these tests fail on Linux in #111179 (comment) .

[Zalathar]

Per https://github.com/rust-lang/rust/actions/runs/5276267731/jobs/9542755469?pr=112514 , the test seems to succeed on Linux even on current master, without my migration to run-coverage.

[Zalathar]

I'll do another test run on Linux (this time with no changes to bootstrap), just for good measure.

[Zalathar]

Now that I've said #112300 is ready to merge, I want to run one last cross-platform check to make sure that nothing has mysteriously broken over the last few weeks.
