Thanks, I wasn't aware of that. At a glance, it looks like that patch implements `DstWidth != SatWidth` and vector types; I left that as a TODO, hoping to seek feedback on the overall approach first. I think they'll be fairly clean incremental changes but I can roll them into this patch if that's preferred.

By the way, the use-case for this is Rust, which has well-defined sematics for FP-to-integer casts so this becomes a fairly common operation.
