```
Sema: don't rely on Liveness

We're currently experimenting with backends which effectively do their
own liveness analysis, so this old trick of mine isn't necessarily valid
anymore. However, we can fix that trivially: just make the "nop"
instruction we jam into here have the right type. That way, the leftover
field/element pointer instructions are perfectly valid, but still
unused.

```
