* valprint.h (get_array_bounds): Renames get_array_low_bound.

    * valprint.h (get_array_bounds): Renames get_array_low_bound.
        * valprint.c (get_array_bounds): Renames get_array_low_bound.
        Return the proper bound value if the array index type is an
        enumerated type. Compute the high bound if requested.
        (val_print_array_elements): Handle the case when the array
        element has a null size.
        * ada-valprint.c (print_optional_low_bound): Add handling
        for empty arrays or arrays of zero-size elements.
        (ada_val_print_array): New function, extracted out from
        ada_val_print_1 case TYPE_CODE_ARRAY, and enhanced to
        handle empty arrays and arrays of zero-size elements.
        (ada_val_print_1)[case TYPE_CODE_ARRAY]: Replace extracted-out
        code by call to ada_val_print_array.
        (ada_value_print): Remove handling of null array.  The handling
        was incomplete and is now better handled by ada_val_print_array.
