[kingslef]

The test fails on 1.36.0 but passes on master.

Huge thanks for @hellow554 actually digging out the minimized version of the
repro.

Fixes #60976.

Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @nikomatsakis (or someone else) soon.

If any changes to this PR are deemed necessary, please add them as extra commits. This ensures that the reviewer can see what has changed since they last reviewed the code. Due to the way GitHub handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed. Large or tricky changes may require several passes of review and changes.

Please see the contribution instructions for more information.

So, passes nicely with master:

$ ./x.py test --stage 1 src/test/ui --test-args extern-use-primitive-type
...
running 1 test
.
test result: ok. 1 passed; 0 failed; 0 ignored; 0 measured; 9546 filtered out

        finished in 8.265
Build completed successfully in 0:00:13

and fails as expected on 1.36.0

$ ./x.py test --stage 1 src/test/ui --test-args extern-use-primitive-type
...
