This prevents crashes in the OpenMP offload pipeline as not everything is properly annotated with debug information, e.g., the runtimes we link in. While we might want to have them annotated, it seems to be generally useful to gracefully handle missing debug info rather than crashing. TODO: A test is missing and can hopefully be distilled prior to landing. This fixes #51079. Differential Revision: https://reviews.llvm.org/D116959
