note_stores will let you know about each store, not use of expression you are
interested in.  With note_uses you are notified about the USE expressions as
well as the non-0 operands of SIGN_EXTRACT/ZERO_EXTRACT.
Note_uses is kind of reverse for note_stores.

When doing cprop, you want to propagate into these as well.

Note that I am leaving in few minutes to Prague and won't be able to reach
email till tomorrow or monday. So if you will OKay the patch, can you please
install it as well to avoid people from having bootstrap troubles?
