[PATCH] D52952: [IR][Modules] Improve quality of diagnostic messages for non-fatal warnings during module linking.

Spoke with @dblaikie, appreciate the explanation, seems I had Clang pcm modules and LLVM IR modules mixed up hence the confusion over modulemaps. The actual issue boiled down to a build system update/migration and `-dwarf-4` being dropped into the default set of build flags, and then undone shortly after, but not before some IR archives were recompiled, which caused the downstream issue I've been trying to hunt down, with some modules ending up with wrong metadata. Thank you for finishing the revision, should be easier to diagnose if anyone runs into a similar type of problem in the future.
