kernel - Enhance CPUMASK and atomic ops

* Add atomic_testandset_long()
  Add atomic_testandclear_long()

* Add atomic_cmpxchg_long_test().  This is for debugging only, it uses the
  'z' flag instead of comparing old-vs-result.  But they should have the
  same effect.

* Add macros for atomic_store_rel_cpumask() and atomic_load_acq_cpumask().

* Add ATOMIC_CPUMASK_TESTANDSET()
  Add ATOMIC_CPUMASK_TESTANDCLR()
  Add ATOMIC_CPUMASK_COPY()
