I think it is clear by now that the new linker is viable.

These functions are "constructors" of the LinkingContexts. We already
have auxiliary classes and functions for ELFLinkingContext in the header.
They fall in the same category.

What we are doing in ELFTarget.h was dubious. In the file, we define
partial classes of <Arch>LinkingContexts to declare only static member
functions. We have different (complete) class definitions in other files.
They would conflict if they exist in the same compilation unit (because
the ones defined in ELFTarget.h has only static member functions).
I don't think this was valid C++.

<Arch>ELFLinkingContext.
registerRelocationNames() function is called to register all known
ELF relocation types to the central registry. Since we have separate
LinkingContext class for each ELF machine type, we need to call the
function for each LinkingContext.
However, the function belonged to TargetHandler instead of LinkingContext.
So we needed to do ctx.getTargetHandler().registerRelocationNames().
This patch removes that redundant getTargetHandler call by moving the
function from TargetHandler to LinkingContext.
Conceptually this patch is small, but in reality it's not that small.
It's because the same code is copied to each architecture.
Most of this patch is just repetition. We need to merge them, but
that cannot be done in this patch.

In r233772, I removed an empty class, DefaultTargetHandler, from
the class hierarchy by merging the class with TargetHandler. I then
found that TargetHandler and its base class, TargetHandlerBase,
are also almost the same.
We need to go deeper.
In this patch, I merged TargetHandlerBase with TargetHandler.
The only difference between them is the existence (or absense)
of a pure virtual function registerRelocationName(). I added that
function to the (new) TargetHandler.
One more thing is that TargetHandler was templated for no reason.
I made it non-templated class.

lldELF is used by each ELF backend. lldELF's ELFLinkingContext
also held a reference to each backend, creating a link-time
cycle. This patch moves the backend references to lldDriver.

The LLD linker searches initializer and finalizer function names
and emits DT_INIT/DT_FINI dynamic table tags to point to these symbols.
The -init/-fini command line options override initializer ("_init") and
finalizer ("_fini") function names used by default.
Now the -init/-fini options do not affect .init_array/.fini_array
sections. The corresponding code has been removed.

This would permit the ELF reader to check the architecture that is being
selected by the linking process.
This patch also sorts the include files according to LLVM conventions.

This patch adds the initial ELF/AArch64 support to lld. Only a basic "Hello
World" app has been successfully tested for both dynamic and static compiling.
