Similar to issue 21945, but this is for structs and unions that define no
instances.

---
struct { int var; };
typedef struct { int var };
---

Both examples produce warnings with a C compiler as they are no-op.  It should
perhaps be an error with D though, as such declarations are semantically
invalid, as per the assertions that it triggers.
