PR tree-optimization/66856
* tree-vect-loop.c (vect_transform_loop): Free SLP instances here.
* tree-vect-slp.c (vect_free_slp_tree): Decrement stmt reference count.
(vect_create_new_slp_node): Increment stmt reference count.
(vect_get_and_check_slp_defs): Make sure stmts are nor already in
an SLP tree before swapping operands.
(vect_build_slp_tree): Likewise.
(destroy_bb_vec_info): Free stmt info after SLP instances.
* tree-vect-stmts.c (new_stmt_vec_info): Initialize reference count.
* tree-vectorizer.h (struct _stmt_vec_info): Add num_slp_uses field.
(STMT_VINFO_NUM_SLP_USES): New macro.
