// Trace probes dispatching to various tracing frameworks
//
// In order to avoid accumulating multiple calls to tracing calls at trace
// points, we define inline probe functions that contain the various
// invocations.
//
// Dtrace - dtrace probes are unconditionally added as probe activation is
//   handled by the dtrace component of the kernel, and inactive probes are
//   very cheap — usually, one no-op.  Consequently, dtrace can be used with
//   all flavours of the RTS.  In addition, we still support logging events to
//   a file, even in the presence of dtrace.  This is, eg, useful when tracing
//   on a server, but browsing trace information with ThreadScope on a local
//   client.
