ChangeLog entry is misformatted.  You need to specify each function in the 
file and what changed.  The patch itself looks fine.

In ipa-cp.c:constant_val_insert it'd be safer to use fold_convert to adjust 
for minor type variations (like the short/int that was causing you grief 
earlier).  Something like this:
