Add a test for the dmb instruction on ARM

The dmb instruction is used to implement a memory barrier on modern
ARM hardware.  The older generations of processors which are included
in single processor systems can get by on the generic implementation
of the cmm_mb().  This will allow the user space rcu to work on many
other ARM systems.
