ELFObjectWriter: Don't sort local symbols

Browse Source 
GNU as does not sort local symbols. This has several advantages:

* The .symtab order is roughly the symbol occurrence order.
* The closest preceding STT_SECTION symbol is the definition of a local symbol.
* The closest preceding STT_FILE symbol is the defining file of a local symbol, if there are multiple default-version .file directives. (Not implemented in MC.)
