Remove all the atomic code besides MSVC and std::atomic

[ChangeLog][Important Behavior Changes] Starting with Qt 5.7, Qt requires a C++11 compiler with support for C++11 atomics. This affects user code too: Qt headers no longer compile with a C++98 compiler. The minimum compiler versions for this release are: * Clang 3.4 (found in XCode 5.1) * GCC 4.7 * Microsoft Visual Studio 2012 Change-Id: Ib056b47dde3341ef9a52ffff13ef1f496ea9363f Reviewed-by: Marc Mutz <[email protected]> Reviewed-by: Dmitry Shachnev <[email protected]>
