Boaz Brickner 6a99c4e970 When diagnosing a duplicated name, add the name to the diagnosis (#4902) 
In order to have the name available for diagnostics, we now always set
`NameId` in `NameContext` and put `poisoning_loc_id` as part of the
union with `resolved_inst_id` instead (since we never need both).
