re PR tree-optimization/39698 (wrong types for vectorized reduction)

PR tree-optimization/39698
* tree-vect-loop.c (get_initial_def_for_reduction): Use the
type of the reduction variable. Only generate the def if
it is needed.
* omp-low.c (expand_omp_for_generic): When converting to a pointer
make sure to first convert to an integer of the same precision.
* tree-vect-loop-manip.c (vect_update_ivs_after_vectorizer): Retain
the type of the evolution correctly in computing the new
induction variable base.
