Comment (by simonpj):

 I see sense in this, but I recall lots of to-and-fro about exactly when to
 distinguish signed (`Int`) from unsigned (`Word`) values.  See
 particularly `Note [Signed vs unsigned]` in `cmm/CmmType`.

 I'm not arguing on way or another here, just mentioning that the
 signed/unsigned choice ripples surprisingly far.
