RFR(M): 8008555: Debugging code in compiled method sometimes leaks memory

> Virtual methods add vtable field to CodeString. I think we can have _offset in CodeString instead and use it to distinguish comments (_offset >= 0). It will simplify the code since you don't need CodeComment class.

Thanks for the suggestion. What about this:
