[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.

[lld][Core] Fix latch synchronization bug.
...
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.

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.
