* exp_ch7.adb (Expand_Ctrl_Function_Call): Remove incorrect special
case for the case of an aggregate component, the attach call for the
result is actually needed.
* exp_aggr.adb (Backend_Processing_Possible): Backend processing for
an array aggregate must be disabled if the component type requires
controlled actions.
