```
Sema: provide source location when analyzing panic handler

The panic handler decl_val was previously given a `unneeded` source
location, which was then added to the reference trace, resulting in a
crash if the source location was used in the reference trace. This
commit makes two trivial changes:

* Don't add unneeded source locations to the ref table (panic in debug, silently ignore in release)
* Pass a real source location when analyzing the panic handler

```
