Good catch.

Does it work instead to move the 

      /* An unsigned comparison against 0 can be simplified.  */

and 

      /* Comparisons with the highest or lowest possible integer of
         the specified size will have known values and an unsigned
         <= 0x7fffffff can be simplified.  */

tests up?
