	* sem_ch3.adb (Analyze_Subtype_Declaration): A subtype
	declaration with no aspects, whose subtype_mark is a subtype
	with predicates, inherits the list of subprograms for the type.

	* exp_aggr.adb (Has_Per_Object_Constraint): Refine previous
	change.

	* lib-writ.adb (Write_ALI): Do not record in ali file units
	that are present in the files table but not analyzed. These
	units are present because they appear in the context of units
	named in limited_with clauses, and the unit being compiled does
	not depend semantically on them.

	* sem_ch6.adb (Analyze_Subprogram_Body_Helper): Simplify code to
	create the procedure body for an function returning an array type,
	when generating C code. Reuse the subprogram body rather than
	creating a new one, both as an efficiency measure and because
	in an instance the body may contain global references that must
	be preserved.
