I've managed to fix the issue around unused `func.func` arguments by handling them explicitly.

Therefore, I handle this case in a generic way with `mlir.regionArgNames`.

Also, following your suggestion around the how AsmOpInterface behaves, I added a test case where I set names that would explicitly clash with an contradict default anonymous names (e.g. `%arg0`, `%cst_1`, `%1`, etc).
