DEBUG_TYPE is already defined at the beginning of this file. We don't
want to have two different debug flags for a single pass.

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.

This patch splits X86_64Target specific code so that 
the dynamic atoms and the Relocation handlers are in seperate 
files for easier maintenace. The files are sure to grow and this 
makes it easier to work with.

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
actually changed the layout.

We need to acquire a lock before signal a condition.
Otherwise threads waiting on a condition variable can
miss a signal.

Consider two threads: Thread A executing dec() and thread
B executing sync(). The initial value of _count is 1. If
these two threads are interleaved in the following order,
thread B misses the signal sent by thread A, because at the
time thread A sends a signal, B is not waiting for it.

  Thread A                 |   Thread B
                           |   std::unique_lock<std::mutex> lock(_condMut);
                           |   while (!(_count == 0)) {
  if (--_count == 0)       |
    _cond_notify_all()     |
                           |     _cond.wait();
                           |   }

Note that "wait(lock, pred)" is equivalent to "while(!pred())
wait(lock)", so I expanded it in the above example.
