Shankar Easwaran 2302bd5568 [lld] rename member variable name. 
This renames variable name to reflect initial undefined symbols that are
defined by the linker -u option.

This doesnot change any functionality in lld, and updates code to reflect
Nick's comment.

Rui Ueyama 9e56839a83 [lld][PECOFF] Add WinLinkDriver and PECOFFTargetInfo. 
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.

Shankar Easwaran eeee23e60a This adds functionality for undefined atoms from dynamic libraries to be added 
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.

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 6580d1f226 Set ordinals correctly. 
This actually doesn't change behavior with the current LinkerInvocation, but
it's needed when you make reading parallel.
