* psppire-dict.c (psppire_dict_dump): Don't use

* psppire-dict.c (psppire_dict_dump): Don't use
dict_get_compacted_dict_index_to_case_index, as that function has
been deleted.

* flip.c: Drop use of dict_get_compacted_dict_index_to_case_index
and just use the ordinary case indexes.  There seemed to be no
reason for the former method.

* get.c (case_map_get_value_cnt): New function.

* dictionary.c (dict_compact_values): Don't delete scratch
variables as well as compacting case indexes.  Update all callers.
(dict_get_compacted_value_cnt): Rename dict_count_values and
change interface.  Update all callers.
(dict_get_compacted_value_cnt): Remove.
(dict_compacting_would_shrink): Remove.
(dict_compacting_would_change): Remove.
(dict_make_compactor): Add new parameter.  Update all callers.

* procedure.c (proc_casereader_read): Use casewriter_get_value_cnt
instead of dict_count_values, changing an O(N) operation into
O(1).
