The only difference between the two is a `dyn_cast<>` to `GlobalVariable`. If optimizations have left anything behind when a global gets replaced, then it doesn't seem like the debug info is dead. I can't seem to find an optimization that would leave behind a non-`GlobalVariable` without nulling the reference entirely, so I haven't added a testcase (but I'll be deleting `getGlobal()` in a future commit). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@234792 91177308-0d34-0410-b5e6-96231b3b80d8
