    Fix incorrect SLOC on instruction
    
    This puts the missing SLOC on a statement generated by a return.
    
    gcc/ada/
            * gcc-interface/trans.c (gnat_to_gnu) <N_Simple_Return_Statement>:
            Put a SLOC on the assignment from the return value to the return
            object in the copy-in/copy-out case.
