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 d8da989e78 [lld][LayoutPass] An earlier commit moved the functionality so that Atoms would
be laid out by their ordinal overrides first, there was a bug that two atoms may 
get the same override index due to which atoms were not ordered properly. This
commit fixes the problem.

Now the atoms are ordered by 

- Section Position hints
- Atom override (Using layout-after/layout-before/in-group)
- Content Permissions
- Content Type
- File Ordinal

This also fixes the problem of running c++ static executables that 
was broken by an earlier patch.

Shankar Easwaran 9af77a2cab [lld][ELF][All Archs] Addend is used by dynamic relocations
only if they are relative. This removes the FIXME when the
relocations are being emitted and checks if the relocation
is relative and only then populates the addend information.

I couldnt add a testcase for this as llvm-readobj lacks     
functionality of printing dynamic relocations.              

When the functionality is added, remove the commented lines
from elf/ifunc.test to test functionality.

Shankar Easwaran 3c5d2c8a24 [lld][LayoutPass] This commit fixes a problem in the
Layoutpass by ordering atoms if they appear in the override
list first and then looking at the way of ordering atoms in
the default way.

The fix also fixes issues with the sizes of the sections,
that appear in the output properly too.

The commit also adds a testcase(orderatoms-by-override.test)
to test it and fixes all the other relevant testcases.

Also shuffle the atoms so that it can verify the layout pass

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.
