Rafael Espindola e7a00e326a For now we only have on Chunk type. Simplify.
The others we have in sight are
* common symbols.
* entries in SHF_MERGE sections.

They will have a substantially different treatment. It is not clear if it is
worth it putting them all in a single list just to dispatch based on the kind on
the other side.

I hope to implement common symbols soon, and then we will be in a position
to have a concrete discussion. For now this is simpler for the the implemented
features.

Rafael Espindola 87ee8dcb64 Use ELFOSABI_NONE. This matches both bfd ld and gold.

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.
