Rui Ueyama 8ecb0b68c1 ELF: Make createWriterELF's type consistent with other functions.
Other createWriter<Arch> functions take <Arch>LinkingContext as arguments.
Only createWriterELF was an exception. This patch makes it consistent with
others.

Rui Ueyama c8dad8e324 ELF: Remove TargetHandlerBase by merging it with TargetHandler.
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.

Greg Fitzgerald 4b6a7e355b Fix five of the shared library build targets
Before this patch there was a cyclic dependency between lldCore and
lldReaderWriter.  Only lldConfig could be built as a shared library.

* Moved Reader and Writer base classes into lldCore.
* The following shared libraries can now be built:
     lldCore
     lldYAML
     lldNative
     lldPasses
     lldReaderWriter

Shankar Easwaran ac23808619 [ELF] Add Readers for all the ELF subtargets.
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.

Shankar Easwaran 7915ff34b7 [lld][LinkingContext][ELF] Allow different output file types.
This adds an option --output-filetype that can be set to either
YAML/Native(case insensitive). The linker would create the outputs
associated with the type specified by the user.

Changes all the tests to use the new option.

Nick Kledzik c314b46e71 This is my Driver refactoring patch.
The major changes are:
1) LinkerOptions has been merged into TargetInfo
2) LinkerInvocation has been merged into Driver
3) Drivers no longer convert arguments into an intermediate (core) argument 
   list, but instead create a TargetInfo object and call setter methods on 
   it. This is only how in-process linking would work. That is, you can 
   programmatically set up a TargetInfo object which controls the linking.
4) Lots of tweaks to test suite to work with driver changes
5) Add the DarwinDriver
6) I heavily doxygen commented TargetInfo.h

Things to do after this patch is committed:
a) Consider renaming TargetInfo, given its new roll. 
b) Consider pulling the list of input files out of TargetInfo. This will 
   enable in-process clients to create one TargetInfo the re-use it with 
   different input file lists.
c) Work out a way for Drivers to format the warnings and error done in 
   core linking.

Michael J. Spencer db18847b01 [ELF][Writer] Refactor Section to not have atoms. Move atoms into AtomSection.
The purpose of this change is to simplify creating non-atom sections.
Previously _contentType, _sectionKind and _order were used for multiple
purposes and collided in places. This moves all of the Atom specific logic down
into AtomSection and makes Section just have raw Elf_Shdr flags.
