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.
