  Log:
  Use "iq" instead of "ir" for the register constraint.  "iq" means 'an
  integer constant or one of %ax,%bx,%cx, or %dx.  The prior use of "ir"
  could cause GCC to attempt to use a 'low byte' accessor on a register
  that cannot be accessed that way, such as '%si' (e.g. %sil).  I see no
  need to get fancy so I am just applying %iq to all the atomic instructions.
  It's good enough.
