2019-08-14  Ed Schonberg  <schonberg@adacore.com>

* sem_aux.adb (Next_Rep_Item): If a node in the rep chain
involves a Ghost aspect it may have been replaced by a null
statement; use the original node to find next Rep_Item.
* repinfo.adb (List_Entities): Do not list an Ignored
Ghost_Entity, for which information may have been deleted.
