Subject: [PATCH] Define special members as defaulted

This adds defaulted definitions for a few more types where implicitly
declaring them is deprecated (as discussed at the WG21 meeting this
week).

	* include/bits/ios_base.h (ios::Init::Init(const Init&))
	(ios::Init::operator=): Define as defaulted.
	* include/bits/stl_bvector.h (_Bit_reference(const _Bit_reference&)):
	Likewise.
	* include/bits/stream_iterator.h (istream_iterator::operator=)
	(ostream_iterator::operator=): Likewise.
	* include/bits/streambuf_iterator.h (istreambuf_iterator::operator=)
	Likewise.
	* include/std/bitset (bitset::reference::reference(const reference&)):
	Likewise.
	* include/std/complex (complex<float>::complex(const complex&))
	(complex<double>::complex(const complex&))
	(complex<long double>::complex(const complex&)): Likewise.

Tested powerpc64le-linux, committed to trunk.
