* tree-vect-loop.c (check_reduction_path): Check we can compute
reduc_idx.
(vect_is_simple_reduction): Set STMT_VINFO_REDUC_IDX.
* tree-vect-patterns.c (vect_reassociating_reduction_p): Return
operands in canonical order.
* tree-vectorizer.c (vec_info::new_stmt_vec_info): Initialize
STMT_VINFO_REDUC_IDX.
* tree-vectorizer.h (_stmt_vec_info::reduc_idx): New.
(STMT_VINFO_REDUC_IDX): Likewise.
