trace: [tcg] Generate TCG tracing routines
Generate header "trace/generated-tcg-tracers.h" with the necessary routines for
tracing events in guest code:
* trace_${event}_tcg
Convenience wrapper that calls the translation-time tracer
'trace_${event}_trans', and calls 'gen_helper_trace_${event}_exec to
generate the TCG code to later trace the event at execution time.
