[5/n] PR85694: Remove dead WIDEN_SUM handling
vect_recog_dot_prod_pattern and vect_recog_sad_pattern both checked
whether the statement passed in had already been recognised as a
WIDEN_SUM_EXPR pattern. That isn't possible (any more?), since the
first recognised pattern wins, and since vect_recog_widen_sum_pattern
never matches a later statement than the one it's given.

gcc/
* tree-vect-patterns.c (vect_recog_dot_prod_pattern): Remove
redundant WIDEN_SUM_EXPR handling.
(vect_recog_sad_pattern): Likewise.
