Added tests for AT_specification and AT_abstract origin.

@clayborg I didn't change the implementation because IIUC the "parsed DIE" is merely a structure with computed parent/child/sibling relationship, we don't build any data structures for the attributes themselves. 

If we were to go through the parsed DIE (i.e. `DWARFDIE` instead of `DIERef`), the implementation will still boil down to the same thing, so we would be adding one more code path to `PeekDIEName` without any benefits. Does that make sense?
