<pre>UpgradeDebugInfo will drop all the old debug info it can see.
Unfortunately, if the module is being lazily loaded, it will miss stuff from
the function bodies.
When the bodies are finally read, the module becomes invalid.
This manifests as a crash in ~/llvm/llvm/test/tools/gold/drop-debug.ll</pre>
