[PATCH] Implement DRs 60 and 63

This patch implements DR 63 (TC) and those parts of DR 60 (TC) that refer
to ostream manipulators and unformatted output functions.

I'm assuming that "does not behave as an [un]formatted output function"
in DR 60 means:

* Don't construct sentry objects
* Don't catch exceptions

Tested on i686-pc-linux-gnu.

	* include/bits/ostream.tcc
	(basic_ostream::operator<<(basic_ostream& (*)(basic_ostream&)),
	basic_ostream::operator<<(basic_ios& (*)(basic_ios&)),
	basic_ostream::operator<<(ios_base& (*)(ios_base&))):
	Implement the resolution of DR 60 (TC): These are not formatted
	output functions so don't construct sentry objects and don't
	catch exceptions.
	(basic_ostream::put, basic_ostream::write): Implement the
	resolution of DR 63 (TC) by catching exceptions and setting
	(basic_ostream::flush): Implement the resolution of DR 60 (TC):
	This is not an unformatted output function so don't construct
	a sentry object.
	* testsuite/testsuite_io.h (sync_streambuf): Define.
	* testsuite/27_io/basic_ostream/flush/char/ New test.
	* testsuite/27_io/basic_ostream/inserters_other/char/ New test.
	* testsuite/27_io/basic_ostream/put/char/ New test.
	* testsuite/27_io/basic_ostream/write/char/ New test.
