formatter.h (_GLIBCXX_TYPEID): New macro to simplify usage of typeid. 

2015-05-20  François Dumont  <fdumont@gcc.gnu.org>

	* include/debug/formatter.h (_GLIBCXX_TYPEID): New macro to simplify
	usage of typeid.
	(_Error_formatter::_M_print_type): New.
	* src/c++11/debug.cc
	(_Error_formatter::_Parameter::_M_print_field): Use latter.
	(_Error_formatter::_M_print_type): Implement latter using
	__cxaabiv1::__cxa_demangle to print demangled type name.
