* string.c (rb_str_cmp_m): return nil if str2 does not respond to

  both "to_str" and "<=>".

* compar.c (cmp_gt): return nil if "<=>" returns nil (means
  incomparable).

* compar.c (cmp_ge): ditto.

* compar.c (cmp_lt): ditto.

* compar.c (cmp_between): use RTEST(), since cmp_lt and cmp_gt may
  return nil.
