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 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.

Michael J. Spencer cfe59fd0d3 [Driver] Replace Target with TargetInfo. Simplify LinkerInput. 
This removes Target and moves the functionality it had over to TargetInfo.

This also simplifies LinkerInput by removing the InputKind. This will be handled elsewhere.

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.

Chandler Carruth b5f3bd956c Replace the 'final' keyword with 'LLVM_FINAL' as GCC 4.6 doesn't support 
the keyword.

If anyone cares deeply about the final optimizations with GCC, we might
want to add a version test to the LLVM definition, but I'm perfectly
happy with this just only firing under Clang and modern MSVC builds.

so that they have the same address.

Sid Manning 42064e5b60 * Add relocation reference support for Hexagon and PowerPC. 
- Hexagon has many relocation types, this patch covers just
