bitset: Do not derive from _Safe_sequence_base in C++0x mode... 

2010-11-07  Paolo Carlini  <paolo.carlini@oracle.com>

	* include/debug/bitset: Do not derive from _Safe_sequence_base in
	C++0x mode, otherwise std::bitset isn't a literal type anymore;
	adjust everywhere.

	* include/debug/bitset (bitset<>::bitset(), bitset<>::
	bitset(unsigned long long)):  Add missing constexpr specifier.
