/// call in every function in the whole module and tries to inline if
/// profitable. With this module level inliner, it is possible to evaluate more
/// heuristics in the module level such like PriorityInlineOrder. It can be
/// tuned with a number of parameters to control what cost model is used and
/// what tradeoffs are made when making the decision.
