// Note: There is a difference here between OGCG and the CIR->LLVM path. OGCG
//       generates calls rather than invokes for getSource and the unique_ptr
//       because the temporary hasn't been constructed yet and therefore doesn't
//       need to be cleaned up. CIR generates invokes, but because we haven't
//       set the cleanup active flag yet, the EH cleanup will resume without
//       doing anything, so this is effectively equivalent to the OGCG behavior.
//       Curiously, OGCG generates an invoke for the Wrapper::empty() call,
//       even though that also doesn't activate the cleanup.
