@erichkeane The existing behavior is to call explicit specializations "partial
specializations" in the diagnostic for unexpanded parameter packs. This patch
fixes that, so a distinction is made between partial/explicit specializations.
For example, the test on line 391 displays different behavior:
```cpp
struct InnerClass<Ts>; // expected-error{{explicit specialization contains
unexpanded parameter pack 'Ts'}}
```
Note "explicit specialization" in the diagnostic.
