there were actually two patches of mine in this direction. The first one
was far too much ambiguous and did too much things at once (I meant it
basically as a rfc and a proof of the concept). The second one did
something quite similar to this one (cut passes into helper functions
with a standardized interface), but it was rejected as too complicated
to review at once and I did not have a time to try to push it in in
a pass-by-pass fashion.
