commit-bot@chromium.org 64f6d15451 Use SkAtomics_sync on Android 
Every doc I've found about using Android's atomics says, "stop".

"* A handful of basic atomic operations.  The appropriate pthread
 * functions should be used instead of these whenever possible."

"... we recommend stopping from using these functions entirely. Very fortunately, GCC provides handy intrinsics functions that work with very reasonable performance and always provide a full barrier."

As far as I can tell, there's no code generation change here: both the __sync atomics and the android_ atomics use full memory barriers.  (And now with this all unified, it'll be easier to get the real wins by switching everything to __atomic atomics, which are like __sync atomics but allow control over memory barriers.)
