	* tree-vect-loop.c (vect_create_epilog_for_reduction): Use
	STMT_VINFO_REDUC_IDX from the actual stmt.
	(vect_transform_reduction): Likewise.
	(vectorizable_reduction): Compute the reduction chain length,
	do not recompute the reduction operand index.  Remove no longer
	necessary restriction for condition reduction chains.
