Start adding support for shared libraries.

This just adds the types and enough support to detect incompatibilities among
shared libraries and object files.

Delete SyntheticUndefined.

Now that resolved is templated anyway, we can use the regular Undefined.

Keep the largest common symbol.

This requires templating some functions over ELFT, but that opens other cleanup
opportunities for future patches.

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.

The SymbolTable doesn't need to be a template.

It was already using just code that is common to all object files.

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.
