tests: Test line number in debuginfo for diverging function calls

Closes rust-lang#59558 which just [E-needs-test](rust-lang#59558 (comment)).

The bug seems to have been fixed in **nightly-2021-05-10**:

```sh

                 nightly-2021-05-10 \
                 1.88; do
    echo -e "\nWith $toolchain:"

done
```

```
With nightly-2021-05-09:

which gives the following list of candidate commits. Not clear which one it is exactly but it doesn't matter much since we can confirm that the test works. I have confirmed locally that with **nightly-2021-05-09** we get `line: 0` for the last call.
