minmax: relax check to allow comparison between unsigned arguments and signed constants
Allow (for example) min(unsigned_var, 20).
The opposite min(signed_var, 20u) is still errored.
Since a comparison between signed and unsigned never makes the unsigned
value negative it is only necessary to adjust the __types_ok() test.
