This will only be true if the definition die has `DW_AT_object_pointer` 
*before* `DW_AT_specification`. `GetAttributes` expands the specification 
attribute "in place", so if the order is reversed, we will encounter the 
attribute from the specification first.

I don't know if there's a good reason for the way that `GetAttributes` works. 
It might be possible to just change it to visit the main DIE first.
