	* exp_util.adb (Activate_Atomic_Synchronization): Do not set
	Atomic_Sync_Required for an object renaming declaration.
	* sem_ch8.adb (Analyze_Object_Renaming): Copy Is_Atomic and
	Is_Independent to renaming object.

	* sem_ch5.adb (Analyze_Iterator_Specification): Diagnose
	various illegalities in iterators over arrays and containers:
	a) New function Get_Cursor_Type, to verify that the cursor is
	not a limited type at the point of iteration.
	b) If the container is a constant, an element_iterator is illegal
	if the container type does not have a Constant_Indexing aspect.
	c) If the iterate function has an in-out controlling parameter,
	the container cannot be a constant object.
	d) Reject additional cases of iterators over a
	discriminant-dependent component of a mutable object.
