Flesh out DIESubprogram a bit more.

- Add accessor for return type.
- Implement DW_AT_artificial parsing.
- Store the subprogram's template parameters and provide accessors
  for them as well. Not used yet but will be handy later if/when we
  want to expose the instantiated types somewhere in the user
  interface when stepping into such a function.
