Explanation: The original code had the assumption we only import modules. However, there is a flag to import an umbrella header in which case the clang nodes have no owning module. This PR prevents a null dereference in that case. Issues: rdar://157489426 Original PRs: #83540 Risk: Low, added a check to avoid null dereference. Testing: Added a compiler test.
