ada: Avoid unused with warning with Extend_System
When the Extend_System pragma is used then we are supposed
to check the extended system for referenced entities. Otherwise
we would get an incorrect unused with warning.
This was previously done on body files but it should also be
done specs as well.
gcc/ada/ChangeLog:
* sem_warn.adb (Check_One_Unit): When a system extension is
present always check entities from that unit before marking
the unit unreferenced.
