[dev.link] cmd/link: support new object file format Parse new object file format in the linker. At least we can link a hello-world program. Add a basic "loader", which handles symbol references in the object file. - mapping between local and global indices - resolve by-name references (TODO: the overwrite logic isn't implemented yet) Currently we still create sym.Symbol rather early, and, after all the object files are loaded and indexed references are resolved, add all symbols to sym.Symbols. The code here is probably not going in the final version. This is basically only for debugging purposes -- to make sure the writer and the reader work as expected.
