* testsuite/20_util/shared_ptr/thread/default_weaktoshared.cc:
Change to mersenne_twister_engine, add same defaults as
mersenne_twister_engine/cons/default.cc.
* testsuite/20_util/shared_ptr/thread/mutex_weaktoshared.cc: Same.
* include/bits/random.tcc (seed_seq::seed_seq): Uglify parameter
to __il.
* include/bits/random.h (mersenne_twister_engine): Qualify
_ShiftMin1 with namespace __detail.
(__detail::_ShiftMin1): Use __gnu_cxx::__numeric_traits::max until
constexpr std::numeric_limits::max() can be used.
(mersenne_twister_engine): Split apart static asserts into one
assert per message. Temporarily disable the last three.
