[27/46] Remove duplicated stmt_vec_info lookups
Various places called vect_dr_stmt or vinfo_for_stmt multiple times
on the same input. This patch makes them reuse the earlier result.
It also splits a couple of single vinfo_for_stmt calls out into
separate statements so that they can be reused in later patches.
