    [Ada] Fix -gnatw.f warnings not having the right insertion characters
    
    This caused these warnings not to be tagged with the switch causing
    them, which is an issue for tools ingesting GNAT's output.
    
    gcc/ada/
    
            * sem_elab.adb (Process_Conditional_ABE_Access_Taken): Add '.f'
            insertion characters.
