Explanation added. For the benchmarks, the one I used was Luxmark, where it gave ~12% better result comparing to standard inliner. For the others it does not look like it makes a lot of sense to try to recollect old HSAIL numbers.
This pass is ported because we know in advance there is an issue like this. As said before cost model is different and some tuning will be also required later when we turn call support on.
