cb8474edae COFF, ELF2: Pass output file path implicitly using Config global variable.
Various parameters are passed implicitly using Config global variable
already. Output file path is no different from others, so there was no
special reason to handle that differnetly.

This patch changes the signature of writeResult(SymbolTable *, StringRef)
to writeResult(SymbolTable *).

afff74e228 ELF2: Simplify Writer interface.
We are using Writer more like a function instead of a class.
This patch makes it a function to simplify the interface.
All details of Writer class is now hidden from other parts of the linker.

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.

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

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

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.

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.
