Ensure that the pointer-sized QAtomicInteger specialization exists

This is already implemented in qatomic_x86.h, qatomic_ia64.h,
qatomic_mips.h, qatomic_armv6.h, and qatomic_cxx11.h. For
qatomic_msvc.h, we've just fixed it.

For qatomic_gcc.h, we know that the compiler supports it, so just add
it. According to the GCC manual, it might print a warning on some
platforms, so we only enable that on 64-bit builds.

For qatomic_unix.h, the support was missing (along with support for
unsigned 32-bit), so this commits adds it.

For qatomic_armv5.h, the platform does not always support 64-bit
atomics, but ARMv5 cannot compile in 64-bit mode anyway.
