Thiago Macieira 7ffcafd1b5 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

Thiago Macieira aba30f0234 Replace the type-based QAtomicIntegerTraits with a size-based one
This simplifies the code a lot and avoids silly mistakes where a
specific integer type is missing (such as char16_t).
