...etTransformInfo in a way similar to how we customize loop unrolling. Use it to provide inliner with target-specific thresholds and other parameters. * augment Inliner pass to use existing TargetTransformInfo API to figure out cost of particular call on a given target. TargetTransforInfo already has getCallCost(), though it does not look like anything uses it. Comments? Concerns? Suggestions?
