Playing around with this, I find it is actually impossible to attach to these
syscall tracepoints from C since they aren't declared anywhere. Plus, since it
looks like they just may be multiplexed inside the "raw" syscall tracepoints,
there wouldn't be any performance improvement using the individual syscall
tracepoints.
