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

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.

64afcb4c6b Move everything over to TargetInfo. 
I really would have liked to split this patch up, but it would greatly
complicate the lld-core and lld drivers having to deal with both
{Reader,Writer}Option and TargetInfo.

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.

6047163a24 [lld] Add support for -mllvm. 
There is no way to test this at the moment because the options are not
processed until the link starts, and we can't pass an empty file.

9ff4be240a Add the core architecture for the lld driver. 
This includes selecting which driver to emulate, option parsing, invocation
building, and running the link. This currently only supports a very basic
subset of ld for x86_64-linux.

lld -flavor ld obj.o -o obj

or symlink lld as (ld , link, ld64, core) to get the desired behavior without
-flavor.
