John Baldwin 2bec909c3d - Fix memory barriers in atomic operations so that the barriers are always
"inside" of locked regions.  That is, an acquire atomic operation will
  always enforce a memory barrier after the atomic operation and a release
  operation will always enforce a memory barrier before the atomic
  operation.
- Explicitly use 'mb' instead of 'wmb' in release atomic operations.  The
  'wmb' memory barrier is not strong enough to guarantee coherence with
  other processors.  This is effectively a nop since alpha_wmb() actually
  performs a 'mb' and not a 'wmb', but I wanted the code to be more
  correct since at some point in the future alpha_wmb()'s implementation
  may switch to being a real 'wmb'.
