Log:
    PR ada/58264
    * gcc-interface/trans.c (Attribute_to_gnu): Define GNAT_PREFIX local
    variable and use it throughout.
    <Attr_Length>: Note whether the prefix is the dereference of a pointer
    to unconstrained array and, in this case, capture the result for both
    Attr_First and Attr_Last.
