18/// The module inliner pass for the new pass manager.
19///
20/// This pass wires together the inlining utilities and the inline cost
21/// analysis into a module pass. Different from SCC inliner, it considers every
22/// call in every function in the whole module and tries to inline if
23/// profitable. With this module level inliner, it is possible to evaluate more
24/// heuristics in the module level such like PriorityInlineOrder. It can be
25/// tuned with a number of parameters to control what cost model is used and
26/// what tradeoffs are made when making the decision.
