Rafael Espindola daa92a6193 Keep the largest common symbol.
This requires templating some functions over ELFT, but that opens other cleanup
opportunities for future patches.

Rafael Espindola 1bd885aba4 ELF: Also record the type of undefined symbols.
Tested with a weak undefined. Testing with a plain undefined will have to wait
for support for -shared.

Rafael Espindola 62b81b875a 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.

Rafael Espindola 3c9cb4b3d3 lld elf2: Diagnose trying to mix incompatible files.
This is also a step in instantiating the writer with the correct template
argument.

Rafael Espindola 2ffdd4d0e5 The SymbolTable doesn't need to be a template.
It was already using just code that is common to all object files.

Rafael Espindola b89951457d 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.

Michael J. Spencer 8a4145411f 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.
