  [ELF] Symbol::replace: use the old nameData/nameSize. NFC

Currently `this->getName() == newSym.getName()`.
By keeping the old nameData/nameSize, newSym's nameData/nameSize will be
ignored. The call sites can avoid calling getName().

printTraceSymbol needs to take the symbol name since `other`'s name is empty.
