Almost no change for bm_so_count_words, but (normal-sized) array and
bighash creation got speedups :o   I prefer this one, but this may
allow too much malloc for some MT users(*).


(*) I plan to cut overall memory use with things like Feature #9614.
    Even if matz requires ordering, we'll still save malloc using
    the linked-list from Feature #9632.
