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.
