LOG: Add test for issue 60486

Close https://github.com/llvm/llvm-project/issues/60486.

When I look back at this problem again, it only appears if we specify it
with `-fmodule-file=<BMI-path>`. And it disappears after we specify it
as `-fmodule-file=<module-name>=<BMI-path>`. Since we want to depreacate
the form `-fmodule-file=<BMI-path>`, we can think the problem goes
away.
