Start adding support for creating shared libraries.
...
They are not fully functional yet, but this implements enough support for lld
itself to read them.
With that, delete the .so binary we were using for tests and start eating our
own dog food.

Start populating the symbol table.
...
With this patch only the name is set. I will set the other fields shortly.
For now the table doesn't include local symbols. This is equivalent to using
--discard-all with gnu ld. This is OK for now since the symbols are not
needed for execution and for testing symbol resolution we only need the
global symbols.

Remove SymbolTable::getChunks.
...
When we were using a std::sort over all the chunks we needed to put them in a
single storage.
Now that we just iterate over them and use a map to find the output section,
we can avoid allocating the temporary storage.

Initial ELF port.

This is a direct port of the new PE/COFF linker to ELF.
It can take a single object file and generate a valid executable that executes at the first byte in the text section.
