There have been reported crashes/hangs with the ordinary
rwlock / spinlocks used by the runtime/translator in the
generated systemtap modules.  Changing them all to the 
raw_* variants makes stap work on preempt-rt.  There may
exist performance/latency drawbacks to this transform,
but we can investigate those as data appears.
