Users can override the default value of the dynamic linker to be set to the
one that appears in the command line. The path can even be empty!. 

Added a test for the option.

The code to actually consume these flags will be added soon.

Add WinLinkDriver and connect it to the existing COFF reader. Remaining
parts are still stubs, so while it can now read a COFF file, it still
cannot link or output PE/COFF files yet.

Suggested by Nick Kledzik in reference to r179590.

Moved llvm_unreachable out of switch blocks to avoid the "control reaches end of non-void function" warning.

to the list of undefined atoms. 

The processing of undefined atoms from dynamic libraries is controlled by
use-shlib-undefines command line option. 

This patch also adds additional command line arguments to allow/disallow
unresolved symbols from shared libraries and mimics GNU ld behavior.

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.

This actually doesn't change behavior with the current LinkerInvocation, but
it's needed when you make reading parallel.

This also adds a simple relocation change for dynamic executables to
x86-64 ELF.

add merge strings option, this temporarily fixes the problem bringing up helloworld with glibc on x86_64

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.

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.

No functionality change.

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.

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.
