	* sem_util.adb (Denotes_Iterator): New routine.
	(Is_Iterator): Code cleanup. Factor out the detection of a
	predefined iterator.  As a result this fixes a missing case
	where a tagged type implements interface Reversible_Iterator.

	* sem_attr.adb (Eval_Attribute): Constant-fold 'Enabled if
	not within a generic unit, even if expander is not active, so
	that instances of container packages remain preelaborable in
	-gnatc mode.

	(__gnat_error_handler): Use trampoline for arm64.

	* exp_ch3.adb (Expand_N_Object_Declaration): if the type of the
	object is a class-wide limited interface type, the expression
	is not restricted to the forms specified for limited types.
