Some evidence to support...I modified the benchmark to pass all
previously recursive calls through an intermediate function. Since
it's fixed-arity with no block, it should directly bind through indy
Perf improves by 2x! That's not enough to bring it back to the
non-ruby-inlining setup, but perhaps it demonstrates that there's an
issue with recursive inlining (for a start).
