3df170b84e [lld][Driver] The driver was creating linker inputs twice
Also add a llvm_unreachable call so that the linker will trip on unhandled
inputElement types.

2f5d64062b [lld] handle the case of errors from createLinkerInput
This changes the interface of createLinkerInput to use ErrorOr, so that
errors from the linker can be captured.

Also adds a convenience function for error strings to be returned from
file nodes.

d26c8e3463 [lld][LinkingContext] Atoms created from command line options should be available in YAML
This adds an API to the LinkingContext for flavors to add Internal files
containing atoms that need to appear in the YAML output as well, when -emit-yaml
switch is used.

Flavors can add more internal files for other options that are needed.

0ca149fce9 Rename TargetInfo -> LinkingContext.
Also change some local variable names: "ti" -> "context" and
"_targetInfo" -> "_context".

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.

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.
