* include/bits/uniform_int_dist.h (_Power_of_two): Add
constexpr.

the wider type is twice as wide as the result type.

and declare variables as constexpr where appropriate.
(uniform_int_distribution:operator()): Likewise. Only consider
the uniform random bit generator's range of possible results
when deciding whether _S_nd can be used, not the __uctype type.
