Use static initialization for QBasicAtomics
A default-constructed static QBasicAtomicInt at function scope
will be dynamically initialized. It will still be zero-initialized,
but at least GCC adds guard variables for such objects.
When using aggregate initialization, the guard disappears.
Amends 04d6495bf773a6bb0d4fa6980df22d3b81a605b0.
