Rafael Espindola aefd5c1617 Create ObjectFile with the correct endian and word size. 
The writer is still hard coded to 64 bits le, but with this we can test for
invalid ELF files.

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.
