	(usum_widen_optab): Likewise.
	* optabs.c (optab_for_tree_code): Add case WIDEN_SUM_EXPR.
	(expand_widen_pattern_expr): New function.
	(init_optabs): Initialize new optabs ssum_widen_optab and
	usum_widen_optab.
	* optabs.h (OTI_ssum_widen, OTI_usum_widen): New optabs.
	(ssum_widen_optab,  usum_widen_optab): New optabs.
	(expand_widen_pattern_expr): New function declaration.
	* tree-pretty-print.c (dump_generic_node): Add case WIDEN_SUM_EXPR.
	(op_prio): Add case WIDEN_SUM_EXPR.
