With the new object files, now we can run the deadcode pass on indices instead of Symbol structs, so we can delay creating Symbols after the deadcode pass. Then we only need to create reachable symbols. Not create Symbols in LoadNew and LoadRefs, and recombine LoadReloc into LoadFull. Split loadcgo into two parts: the first finds root symbols, the second create Symbols and sets attributes. The first runs before the deadcode pass, while the second runs after. TODO: currently there are still symbols that are not marked reachable but still used. This includes DWARF symbols, file symbols, and type symbols that are referenced by DWARF symbols. We still need to create them (conservatively).
