I _think_ that you can unconditionally change the code to do

now, I'm not sure if for the testcase T and unsigned differ in qualifiers.
Do they?

Hmm, I think with the changes I made to the testcase they end up with 
the same qualifiers.  But for constexpr I need to handle them having 
different qualifiers, too.
