* include/std/std_bitset.h (_Base_bitset::_M_do_left_shift,
_Base_bitset::_M_do_right_shift): Expect a non-zero shift.
(bitset::operator<<=, bitset::operator>>=): When shifting more bits
than are in the bitset, zero memory rather than segfault.
(operator>>(basic_istream,bitset): Only call setstate once, after
all work has been done.
* testsuite/23_containers/bitset_members.cc (test03): New test.
* testsuite/23_containers/bitset_shift.cc (test02): New test.
