	attribute should always be transformed into a string literal in
	Analyze_Attribute.
	* par-ch4.adb: Type_Key attribute's type is String; update value of
	Is_Parameterless_Attribute constant to reflect this.
	* sem_attr.adb (Analyze_Attribute): Recognize Type_Key attribute and
	rewrite it as a string literal (attribute value is always known
	statically).
	* snames.ads-tmpl: Add entries for Type_Key attribute.
