  Log Message:
  -----------
  MachO use generic code to detect atomic support.

The default code can detect what width of atomic instructions are supported
based on the targeted architecture profile, version etc so there's no need to
hard-code 64 on Darwin targets (especially as it's wrong in most M-class
cases).
