Log:
	PR c++/92831 - CWG 1299, not extending temporary lifetime for ?:
	* cp-tree.h (extend_ref_init_temps): Add a new argument with NULL
	default arg.
	* call.c (set_up_extended_ref_temp): Add COND_GUARD argument, pass it
	down to extend_ref_init_temps.  Before pushing cleanup, if COND_GUARD
	is non-NULL, create a bool temporary if needed, initialize to false
	and guard the cleanup with the temporary being true.
	(extend_ref_init_temps_1): Add COND_GUARD argument, pass it down
	to recursive calls and set_up_extended_ref_temp.  Handle COND_EXPR.
	(extend_ref_init_temps): Add COND_GUARD argument, pass it down to
	recursive calls and to extend_ref_init_temps_1.

	* g++.dg/cpp0x/temp-extend2.C: New test.
