```
Sema: introduce all_vector_instructions backend feature

Sema is arbitrarily scalarizing some operations, which means that when I
try to implement vectorized versions of those operations in a backend,
they are impossible to test due to Sema not producing them. Now, I can
implement them and then temporarily enable the new feature for that
backend in order to test them. Once the backend supports all of them,
the feature can be permanently enabled.

This also deletes the Air instructions `int_from_bool` and
`int_from_ptr`, which are just bitcasts with a fixed result type, since
changing `un_op` to `ty_op` takes up the same amount of memory.

```
