The spec for integer promotions currently says: "Note: the usual integral
promotions are not performed prior to the complement operation."

However, while this is currently true, it's a deprecation, and is NOT true with
the -transition=intpromote flag. This should be reflected in the spec.

Also, there are no notes for any of the other affected unary expressions about
integer promotion. Those should be added.
