5; Reduced test case from PR35212. Two DISubprogram belong to a different CU but
6; share a scope. Both are declarations and end up in the scope's CU. We want to
7; check that the CU from the context DIE is used (rather than from the IR).
8; This manifests itself by the DW_base_type ending up in the second CU, rather
9; than in the first one as specified in the IR.
