* sem_ch3.adb (Analyze_Subtype_Declaration): if an incomplete
type is tagged, so is a subtype of it.
* sem_ch12.adb (Validate_Actual_Subprogram): implement AI05-0296,
concerning freeze rules in the presence of formal incomplete
types: a formal abstract subprogram cannot have an incomplete
controlling type, and the profile of the actual subprogram does
not freeze if it includes an incomplete untagged type.
