Fix ICE in vec_box lint and add run-rustfix
`hir::Ty` doesn't seem to know anything about type bounds and
`cx.tcx.type_of(def_id)` caused an ICE when it was passed a generic type
with a bound:

```
src/librustc_typeck/collect.rs:1311: unexpected non-type Node::GenericParam: Type { default: None, synthetic: None }
```

Converting it to a proper `Ty` fixes the ICE and catches a few more
places where the lint applies.
