I don't get it, why is this a problem?  Consider if you pass -1 as "unsigned"
to ConstantInt and try to make an i128.  In this case, you'll get 64-bits set. 
If you pass -1 as signed to constant int, you get 128 bits set.

The signedness flag is only useful for constantints > 64 bits (the slow case).
