PR tree-optimization/40436
* ipa-inline.c (leaf_node_p): Implement using is_inexpensive_builtin.
* tree-inline.c (estimate_num_insns): Inexpensive builtins are like
normal instructions; be sure bultin is not implemented in this file;
compute non-zero return cost.
(init_inline_once): Reduce builtin_call_cost to 1; set return cost.
* tree-inline.h (eni_weights_d): Add return cost.
