Thanks for the review @jeanPerier. I think I see the dispatch issue now. Before I rework this, I just want to confirm the intended direction: should this PR focus on fixing the dispatch in `ConvertCall.cpp` so the elemental path is handled consistently with the other paths, rather than trying to handle it inside `HlfirCharExtremumLowering`?
