The functionality is tested in part by replacing `riscv_m_vnot` with `vnot` and having the patterns still match. I've just identified that there are two further RVV patterns which can potentially be updated to use `immAllOnesV` and `immAllZeroV` and will try that out accordingly.

But I would gladly add more testing (for more targets) if someone can help me find a way in.
