History
Chris Mumford 98411c0d33 Added include: libkern/OSAtomic.h 
When building on macOS without gcc (e.g. clang) where HAVE_GCC_ATOMICS
is not defined, `SDL_AtomicTryLock` will call
`OSAtomicCompareAndSwap32Barrier` which is not yet declared.
Including OSAtomic.h on OSX resolves this error/warning:

    SDL_spinlock.c:125:12: error: implicit declaration of function
      'OSAtomicCompareAndSwap32Barrier' is invalid in
      C99 [-Werror,-Wimplicit-function-declaration]
        return OSAtomicCompareAndSwap32Barrier(0, 1, lock);

This was reported in issue #3885 but marked Invalid and closed - possibly
because the default CMake build uses gcc instead of clang.
