(Is_Controlled_Active): New function. * exp_ch3.adb (Expand_Freeze_Record_Type): Use Is_Controlled_Active. * exp_util.adb (Needs_Finalization): Finalization not needed if Disable_Controlled set. * freeze.adb (Freeze_Array_Type): Do not set Has_Controlled_Component if the component has Disable_Controlled. (Freeze_Record_Type): ditto. * sem_ch13.adb (Decorate): Minor reformatting. (Analyze_Aspect_Specifications): Implement Disable_Controlled. * sem_ch3.adb (Analyze_Object_Declaration): Handle Disable_Controlled. (Array_Type_Declaration): ditto.
