LGTM, but this should be further reviewed by someone with more familiarity of the inliner cost model.

I apologize for my lack of understanding. Assuming this isn't obvious to someone more familiar with the inliner cost model, would you mind adding a few comments to this test case explaining exactly what you're testing?
I diffed the output from this test with and without your change and the only cost that was changed was for inner1. Thus, I'm trying to understand the significance of inner2.
