trace: [tcg] Define TCG tracing helper routines
Generates file "trace/generated-helpers.c" with TCG helper definitions to trace events in guest code at execution time. The helpers ('helper_trace_${event}_exec_proxy') cast the TCG-compatible native argument types to their original types (as defined in "trace-events") and call the tracing routine ('trace_${event}_exec').
