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.

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.

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.

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.

In an previous commit I managed to completely disable the IRELATIVE relocation
writing code. I also used the wrong addend for the static relocation. Fix both
these issues and add a test. This test is quite brittle because there's no way
to do arithmetic on variables in FileCheck.
