There is an invariant here that is important to remember:
Except for attributes copied from the top level DIE in the "main"
(or "stub") file in preparation for reading the DWO file
(e.g., DW_AT_GNU_addr_base), we KISS: there is only *one* CU.
Either there isn't a DWO file (in which case this is NULL and the point
is moot), or there is and either we're not going to read it (in which
case this is NULL) or there is and we are reading it (in which case this
is non-NULL). */
