ObjFile::parse combines symbol initialization and resolution. Many tasks unrelated to symbol resolution can be postponed and parallelized. This patch extracts local symbol initialization and parallelizes it. Technically the new function initializeLocalSymbols can be merged into ObjFile::postParse, but functions like getSrcMsg may access the uninitialized (all nullptr) local part of InputFile::symbols.
