I do not like this `DWARFDataExtractor::m_start` modification, it sort of corrupts the `DataExtractor` and various operations stop working then - such as `DWARFDataExtractor::GetByteSize()`. DWZ patch makes from current `dw_offset_t` a virtual (remapped) offset and introduces new physical file section offset which is looked up for data extraction. The file offset is represented as `DWARFFileOffset` in D40474, instead of `bool m_is_dwz;` there could be some `enum { DEBUG_INFO, DEBUG_TYPES, DWZ_DEBUG_INFO } m_where;` instead.
