As the RTL could be = removed fully from the RTL stream and then it will be GC'ed. But machine_function is a GTYed structure, so the reference itself should prevent GC. I don't think we should be in the practice of explicitly ggc_free()ing RTL, since callers don't generally know what other references there might be.=
