Does it have to be at that low language level, then?
Why not carry abstraction further, adjust data definitions,
so that the spaghetti become more manageable? :-)
"Continue that_loop" denotes something, after all.

In addition,  "Continue that_loop" might have other natural
connotations for other people, for example Perl programmers
might feel that a bare jump to some loop's start is inferior
to something like this:

  loop
      ...
      if condition then
          goto loop_end;
      end if;
      ...
    <<loop_end>>
      common_cleanup;
  end loop;

Or consult Knuth, on  Structured Programming with go to Statements.
