OK, that makes sense.  What if we ran the code in expand_end_loop
in the reverse order so that we found the last test in the body
of the loop?  I guess that really makes no difference; without
knowledge of control-flow the lexical order these things appear
in doesn't really mean much.

OK, I agree; this is broken.  I think your marker idea is the
best bet at this point.

Thanks for working this through.
