PR tree-optimization/87105
* tree-vectorizer.h (_slp_tree::refcnt): New member.
* tree-vect-slp.c (vect_free_slp_tree): Decrement and honor
refcnt.
(vect_create_new_slp_node): Initialize refcnt to one.
(bst_traits): Move.
(scalar_stmts_set_t, bst_fail): Remove.
(vect_build_slp_tree_2): Add bst_map argument and adjust calls.
(vect_build_slp_tree): Add bst_map argument and lookup
already created SLP nodes.
(vect_print_slp_tree): Handle a SLP graph, print SLP node
addresses.
(vect_slp_rearrange_stmts): Handle a SLP graph.
(vect_analyze_slp_instance): Adjust and free SLP nodes from
the CSE map. Fix indenting.
(vect_schedule_slp_instance): Add short-cut.
* g++.dg/vect/slp-pr87105.cc: Adjust.
* gcc.dg/torture/20181024-1.c: New testcase.
* g++.dg/opt/20181025-1.C: Likewise.
