My understanding is m_parse_time is the time spent only on parsing the raw data and not about constructing the data structures which will be used by lldb. In https://github.com/llvm/llvm-project/blob/b7611370491873722e08e4ce9374312d0c936af1/lldb/source/Plugins/SymbolFile/DWARF/DWARFUnit.cpp#L223, m_parse_time is used to only track the time spent on parsing a DIE in .debug_info, which also doesn't include the time on constructing necessary data structures. This change is trying to do the same by narrowing the time to just on parsing with llvm.
