Add FileCheck annotations to mir-opt/issues

This resolves a part of #116971 .

The directory `tests/mir-opt/issues` has only one test issue_75439.rs which should add FileCheck annotations.

Originally it was introduced in #75580 to confirm that there were duplicated basic blocks against or-patterns, but in #123067 the duplication was resolved. So FileCheck should ensure that there is no such duplication any more.
