    PR10831: Remember derived "aliases" in the probe chain
    
    SDT and label probes are not really final probe types themselves, but
    rather they get translated into some other final type.  This patch
    preserves this relationship as if SDT and label probes were dynamically
    generated aliases.
    
    * elaborate.cxx (probe::create_alias): New, fake an alias_derived_probe.
    * tapsets.cxx (query_label): Append the label name as an alias.
      (sdt_query::handle_query_module): Let convert_location do the alias.
      (sdt_query::convert_location): Translate the location using an alias.
    * main.cxx (printscript): Elaborate the derivation debug dump.
