Return a varying number of values in IMCC?

[Bob Rogers]

   I don't see a way to do this at present.  What I would like is an
equivalent to .flatten_arg for a PCC return, e.g.:

                .pcc_begin_return
                .flatten_arg array_of_results
                .pcc_end_return

Of course, ".flatten_arg" sounds a bit odd in this context, so calling
it just ".flatten" might be better.  (In which case it might be good to
support ".flatten" as a synonym for ".flatten_arg" in a PCC call.)

   Is this on the right track?
