	* exp_spark.adb (Expand_SPARK_Attribute_Reference):  For
	attributes which return Universal_Integer, introduce a conversion
	to the expected type with the appropriate check flags set.
	* sem_res.adb (Resolve_Range): The higher bound can be in Typ's
	base type if the range is null. It may still be invalid if it
	is higher than the lower bound. This is checked later in the
	context in which the range appears.

	* scos.ads: Introduce a constant to represent ignored
	dependencies in SCO_Unit_Table_Entry.
