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.
