(bst_fail): Use it. (vect_analyze_slp_cost_1): Add visited set, do not account SLP nodes vectorized to the same stmts multiple times. (vect_analyze_slp_cost): Allocate a visited set and pass it down. (vect_analyze_slp_instance): Adjust. (scalar_stmts_to_slp_tree_map_t): New typedef. (vect_schedule_slp_instance): Add a map recording the SLP node representing the vectorized stmts for a set of scalar stmts. Avoid code-generating redundancies. (vect_schedule_slp): Allocate map and pass it down. * gcc.dg/vect/costmodel/x86_64/costmodel-pr83202.c: New testcase.
