All vfnmadd* opcodes were added as well. These are pattern-matched where one of the arguments to the CLIF instruction is an fneg. I opted to not add a new CLIF instruction here since it seemed like pattern matching was easy enough but I'm also not intimately familiar with the semantics here so if that's the preferred approach I can do that too.

I'd generally prefer not to add CLIF instructions if it seems like we can get just as good of results without them. It sounds like that's the case here, so I think you made the right choice.
