[C++11] Replace LLVM atomics with std::atomic.

With C++11 we finally have a standardized way to specify atomic operations. Use
them to replace the existing custom implemention. Sadly the translation is not
entirely trivial as std::atomic allows more fine-grained control over the
atomicity. I tried to preserve the old semantics as well as possible.

Replace the F_Binary flag with a F_Text one.

After this I will set the default back to F_None. The advantage is that

Replace the F_Binary flag with a F_Text one.

After this I will set the default back to F_None. The advantage is that
before this patch forgetting to set F_Binary would corrupt a file on windows.
Forgetting to set F_Text produces one that cannot be read in notepad, which
is a better failure mode :-)

Add a wrapper for open.

This centralizes the handling of O_BINARY and opens the way for hiding more
differences (like how open behaves with directories).

Use the new script to sort the includes of every file under lib.

Sooooo many of these had incorrect or strange main module includes.
I have manually inspected all of these, and fixed the main module
include to be the nearest plausible thing I could find. If you own or
care about any of these source files, I encourage you to take some time
and check that these edits were sensible. I can't have broken anything
(I strictly added headers, and reordered them, never removed), but they
may not be the headers you'd really like to identify as containing the
API being implemented.

Many forward declarations and missing includes were added to a header
files to allow them to parse cleanly when included first. The main
module rule does in fact have its merits. =]

switch from this:

to this:

{

finally, maintain a global list of timer groups, allowing us to
implement TimerGroup::printAll, which prints and resets all active
timers.

add a new TimerGroup::print method, and refactor away the bogus
TimerGroup copy ctor and assignment operator.

rename GetLibSupportInfoOutputFile -> CreateInfoOutputFile and
have it always return a new stream to simplify clients.
