* ada-lang.c (ada_array_bound_from_type): Make non-static.
Handle properly the case when the index type is an enumerated type. Do not return the subtype of the bounds type, just return the bounds type directly - this is not needed and is more consistent with what we do for arrays when no XA parallel type exists.
