It looks like specializations of different kinds are represented in the AST as:
- `FunctionDecl`
- `VarTemplatePartialSpecializationDecl`
- `VarTemplateSpecializationDecl`
- `ClassTemplatePartialSpecializationDecl`
- `ClassTemplateSpecializationDecl`
None of those are subclasses of `TemplateDecl`. That means they wouldn't get
past the `getAsTemplateDecl()` check above, so I'm hesitantly removing this
check.
