(vect_analyze_slp): ... here, forming a true graph with SLP instances being the entries. (vect_detect_hybrid_slp_stmts): Remove wrapper. (vect_detect_hybrid_slp): Use one visited set for all graph entries. (vect_slp_analyze_node_operations): Simplify visited/lvisited to hash-sets of slp_tree. (vect_slp_analyze_operations): Likewise.
