The "C loop method iterations" part might be also useful for reducing the number of exits due to interp_return (which we currently don't consider as side exits). We want such methods to be rewritten in Ruby.

This is really cool!

I have one feature request: when listing the C method calls, can you also list the percentage of total C calls that it represents in parentheses. Might also be nice to show the total count of C calls before the list.

e.g.
Total C calls: 140308043 (100%)
115300 Kernel#is_a? (2.3%)

Nice suggestion 👍 I implemented that in ccf8b44. I also added the results for all headline benchmarks with the latest Ruby in the PR description for convenience.

This looks good to me, and definitely harmless since it's a new separate harness. I'll merge.
