	* sem_disp.adb (Check_Dispatching_Operation): if the dispatching
	operation is a body without previous spec, update the list of
	primitive operations to ensure that cross-reference information is
	up-to-date.

	* sem_ch12.adb (Build_Instance_Compilation_Unit_Nodes): When creating a
	new compilation unit node for the instance declaration, keep the
	context items of the original unit on it, so that the context of the
	instance body only holds the context inherited from the generic body.

	* sem_res.adb: Minor comment fix.
