Shankar Easwaran f9a7933d90 [lld][ELF][X86_64] Reorganize X86_64 Target specific code
This patch splits X86_64Target specific code so that 
the dynamic atoms and the Relocation handlers are in seperate 
files for easier maintenace. The files are sure to grow and this 
makes it easier to work with.

* There is no change in functionality *

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 3e00c5015f [ELF][x86-64] Only emit a PLT entry for a PLT relocation if the target atom is a SharedLibraryAtom.
This seems to be what ld does, but I'm not sure how it works with symbol interposition.

With this hello-world with glibc dynamically linked works.

Michael J. Spencer be03e2a861 [Core,Driver,ELF] Differentiate static and dynamic executables.
This also adds a simple relocation change for dynamic executables to
x86-64 ELF.

Michael J. Spencer 08b49bf27e [ELF][x86-64] Fix ifunc and add test.
In an previous commit I managed to completely disable the IRELATIVE relocation
writing code. I also used the wrong addend for the static relocation. Fix both
these issues and add a test. This test is quite brittle because there's no way
to do arithmetic on variables in FileCheck.

Michael J. Spencer 289dcedea5 [ELF] Add support for IFUNC.
This sadly doesn't have a test for the final
output because llvm-objdump can't dump relocations
that don't belong to a section :(
