It would be nice if we can consistently use `instructions size` instead of `instruction count` in the log too.

Ditto.

Ditto.

Ditto.

I think `machineCodeBytesPerBytecodeWordForBaselineJIT` name becomes wrong now.

Should we rename this to `m_instructionsSize` too?

Thanks for the review. I made you suggested changes except renaming m_instructionCount in the profiler. For that, if we rename it, we should also go through with changing the name throughout the ruby tool
