Clean up supportable_widening_operation.

	* tree-vect-stmts.c (supportable_widening_operation): Remove decl
	parameters.
	(vectorizable_conversion): Update supportable_widening_operation call.
	* tree-vect-patterns.c (vect_recog_widen_mult_pattern): Likewise.
	(vect_recog_widen_shift_pattern): Likewise.
	* tree-vectorizer.h: Update decl.
