#if 0 for DWARFDebugInfo::Find() as it is unused

[jankratochvil]

Summary

I would have to update DWARFDebugInfo::Find() for the DWZ support I am going to submit. But these two methods are currently not used anywhere so there is no way to test them and updating them is then a bit pointless.

Or should the code be removed instead of #if 0?

Feel free to remove any unused code. No need for review on dead code removal. So just remove the code, don't add #if 0
