Introduce a 64-bit atomic ops API

The 64-bit atomic ops API is implemented by
* native word size atomic ops on 64-bit architectures, and
* native double word size atomic ops on 32-bit architectures
  when available. When native double word size atomic is not
  available, the fallback using modification counters is
  used.
Use the new 64-bit atomic ops API
