IIUC, after this PR got merged, all uses of the class below have the same template argument.
What do you think of removing the template?

```
/// Class responsible for emitting a DWARF v5 Accelerator Table. The only

///
/// The class is templated in its data type. This allows us to emit both dyamic
/// and static data entries. A callback abstract the logic to provide a CU
/// index for a given entry, which is different per data type, but identical
/// for every entry in the same table.
template <typename DataT>
class Dwarf5AccelTableWriter : public AccelTableWriter {
