"Process symbol versions" may take 2+% time. "Redirect symbols" may take 0.6% time. This change speeds up the two passes and makes `*sym.getVersionSuffix() == '@'` in the `undefined reference` diagnostic cleaner. Linking chrome (no debug info) and another large program is 1.5% faster. For empty-ver2.s: the behavior now matches GNU ld, though I'd consider the input invalid and the exact behavior does not matter.
