Added files:
	gcc/testsuite/gcc.dg/vect: vect-mult-hi-and-dot.c vect-sad-s8.c 

Log message:
	* tree-vect-analyze.c (vect_pattern_recog_funcs): Move
	vect_recog_sad_pattern to later in the initialization so it could use
	previously detected widen-sum.
	(vect_recog_sad_pattern): Push last_stmt instead of stmt. Check for
	optab of SAD_EXPR (accidentally was MULT_HI_EXPR).
	(vect_recog_mult_hi_pattern): Don't push the widen-mult pattern-stmt
	into the stmt-list.
	(vect_recog_dot_prod_pattern): Rely on previously detected widen-mult
	and widen-sum.
	* tree-vect-transform.c (vectorizable_reduction): Allow other kinds
	of def-types for the uses of the reduction.
