  Log Message:
  -----------
  [ELF] SymbolTable::insert: keep @@ in the name

* Avoid the name truncation quirk in SymbolTable::insert: the truncated name will be replaced by @@ again.
* Allow foo and foo@@v1 in different files to be diagnosed as duplicate definition error (GNU ld behavior)
* Avoid potential redundant strlen on symbol name due to StringRefZ in ObjFile<ELFT>::initializeSymbols
