PR libstdc++/92059 fix several bugs in tr2::dynamic_bitset

	PR libstdc++/92059
	* include/tr2/dynamic_bitset (__dynamic_bitset_base): Define all
	special member functions as defaulted. Add noexcept to most members.
	(__dynamic_bitset_base(size_t, unsigned long long, const _Alloc&)):
	Mask off unwanted bits in the __val parameter. Avoid undefined left
	shifts.
	(__dynamic_bitset_base::_M_assign): Remove.
	(__dynamic_bitset_base::_M_do_reset): Use std::fill.
	(__dynamic_bitset_base::_M_are_all_aux): Avoid integer promotion when
	block_type has lower rank than int.
	(dynamic_bitset): Add noexcept to most members. Use injected-class-name
	in return types and parameter types.
	(dynamic_bitset::_M_Nb): Add default member initializer.
	(dynamic_bitset(), dynamic_bitset(const dynamic_bitset&)): Define as
	defaulted.
	(dynamic_bitset(dynamic_bitset&&)): Clear source object after move.
	(dynamic_bitset::operator=(const dynamic_bitset&)): Define as
	defaulted.
	(dynamic_bitset::operator=(dynamic_bitset&&)): Add noexcept-specifier.
	Define without using swap, to propagate allocator correctly.
	(dynamic_bitset(const char*, const _Alloc&)): Use strlen.
	(dynamic_bitset::_M_do_sanitize, dynamic_bitset::_M_do_fill): Use
	casts to avoid unwanted integer promotions.
	(dynamic_bitset::_M_copy_from_ptr): Rearrange template parameters and
	add default template arguments and default argument to simplify usage.
	(dynamic_bitset::_M_copy_from_string): Adjust call to _M_copy_from_ptr.
	(operator==(const dynamic_bitset&, const dynamic_bitset&))
	(operator<(const dynamic_bitset&, const dynamic_bitset&)): Use _M_Nb.
	* include/tr2/dynamic_bitset.tcc (dynamic_bitset::_M_copy_from_ptr):
	Adjust template parameters to match declaration.
	* testsuite/tr2/dynamic_bitset/cmp.cc: New test.
	* testsuite/tr2/dynamic_bitset/cons.cc: New test.
	* testsuite/tr2/dynamic_bitset/copy.cc: New test.
	* testsuite/tr2/dynamic_bitset/move.cc: New test.
	* testsuite/tr2/dynamic_bitset/pr92059.cc: New test.
