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.

ELF: Drop the Chunk base class.
...
With OutputSection being a virtual interface, each concrete OutputSection
handles only one type of chunk and we don't need a base Chunk class.
So for we have a class that handles input sections and one that handles
the string table, but this extends naturally for other outputs (symbol table,
merging of SHF_MERGE sections, etc.).

Make OutputSection virtual and use that for creating the string table.
...
We were creating the string table in a completely ad hoc way. Now the
string table is an output section and gets its output offset set just like
any other section.
This opens the way for other linker created sections like the symbol table.

Template OutputSection only over Is64Bit.
...
This is a bit more c++ code, but:
* It is less machine code: lld's text is 44688 bytes smaller.
* It should be a bit more efficient in the non native endian case.
* It should be a bit more efficient on architectures with slow unaligned access.

Various parameters are passed implicitly using Config global variable
already. Output file path is no different from others, so there was no

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.
