turn on CPU_CONTROL_SWP_ENABLE.
this allows armv[67] systems to use 'swp' and 'swpb' instructions,
which means they can run armv[45] software.
arm recommends ldrex/strex for armv6 and newer, and it is not
present in armv8 at all or some armv7. we emulate it on armv8 and
need to add emulation for the some armv7. using the hardware is
going to be faster, so, enable this path too.
ok jmcneill.
