Hi,
This is another case of PR123022 and PR116149 where we query a scalar source
operand instead of a vector operand, leading to a wrong AVL during avlprop.
This patch moves viwalu, vfwalu, viwmul, and vfwmul to the proper
bucket. I wonder why I didn't do that the last two times but it seems
to be the correct choice now 🙂
Regtested on rv64gcv_zvl512b and waiting for the CI.
Regards
Robin

Thanks. After confirming the recent failures are unrelated to this
patch I went ahead and pushed it. I'll take care of BZ momentarily.
