I don't want to short-circuit or avoid the discussion about whether we
should actually add these, but I've managed to remove the nasty
DAGCombining bits in favour of a few much simpler patterns. Probably
best that anyone else who does look at the code isn't looking at a
stale version.

Think I'll try to start using Phabricator again next time.

Tim.
