[4.7/4.6] Backport typo fix

[Eric Botcazou]

Having vect_get_single_scalar_iteraion_cost is really not pretty.  This was 
fixed on the mainline only (r188611) so this patch completes the work.

Tested on x86-64/Linux, applied on the 4.7 branch and 4.6 branch as obvious.

        * tree-vectorizer.h (vect_get_single_scalar_iteraion_cost): Fix typo.
        * tree-vect-loop.c (vect_get_single_scalar_iteraion_cost): Likewise.
        (vect_estimate_min_profitable_iter): Adjust to above fix.
        * tree-vect-data-refs.c (vect_peeling_hash_get_lowest_cost): Likewise.
