	* atree.ads, atree.adb: Move New_Copy_Tree.to sem_util.

	* nlists.ads, nlists.adb: Move New_Copy_List to sem_util.

	* lib-load.adb: Use Copy_Separate_Tree rather than New_Copy_Tree

	* sem_util.ads, sem_util.adb: New_Copy_Tree and New_Copy_List belong in
	semantic units, because the handling of itypes in the copied tree
	requires semantic information that does not belong in atree.
