YJIT: Add top ISEQ call counts to --yjit-stats

[k0kubun]

This is the same as #9047 but for ISEQ.

I think it's useful to have the counter for ISEQs when we think about inlining ISEQs. It's also easier to use in production than TracePoint-based counters like Shopify/yjit-bench#163.

Good idea.

I realize this might be annoying to format, but could you also report the full path and line number for ISEQs? Would make it easy to find and go look at the ISEQs.

I realize this might be annoying to format, but could you also report the full path and line number for ISEQs?

In that case, this is the format I want to use 34f4c36, which is the same format as --dump=insns and ISeq#inspect:

This format allows you to naturally print Ruby blocks, which was not possible with the previous format.

I flipped the left and the right of the top-X tables since the label name is way too long to be on the left.

Looks good 👌
