Turns out these were all making `OperandValue::Immediate`s already -- the intrinsic always returns a primitive scalar -- so pretty easy to handle. While I was looking at it, I also "rustified" the intrinsic signature a bit: returning a `bool` and taking a generic pointee and `unsafe fn`s cleans up the call in `std` a bit without making the implementation in the backend any harder.
