N3472 binary constants
	* include/cpplib.h (struct cpp_options): Fix a typo in user_literals
	field comment.  Add binary_constants field.
	* init.c (struct lang_flags): Add binary_constants field.
	(lang_defaults): Add bin_cst column to the table.
	(cpp_set_lang): Initialize CPP_OPTION (pfile, binary_constants).
	* expr.c (cpp_classify_number): Talk about C++11 instead of C++0x
	in diagnostics.  Accept binary constants if
	CPP_OPTION (pfile, binary_constants) even when pedantic.  Adjust
	pedwarn message.

	* g++.dg/cpp/limits.C: Adjust warning wording.
	* g++.dg/system-binary-constants-1.C: Likewise.
	* g++.dg/cpp1y/system-binary-constants-1.C: New test.
