Log message:

	PR c/11658
	PR c/13994
	* Makefile.in (c-parse.o, c-convert.o, c-typeck.o): Depend
	on langhooks.h.
	* objc/Make-lang.in (objc-parse.o): Depend on langhooks.h.
	* c-parse.in, c-convert.c, c-typeck.c, objc/objc-act.c:
	Include langhooks.h.  Replace c_common_truthvalue_conversion
	with the truthvalue_conversion language hook throughout.
	(expr_no_commas): Call default_conversion before save_expr
	for the first term of the production 'x ? : y'.
	* c-common.c (c_common_truthvalue_conversion): Remove
	obsolete block.  Invoke recursively the hook instead
	of this function.
	* c-convert.c (convert): handle ERROR_MARK_NODE.
	* c-typeck.c (build_binary_op): handle ERROR_MARK_NODE
	returned by the truthvalue_conversion language hook.
	* c-lang.c (LANG_HOOKS_TRUTHVALUE_CONVERSION): Use
	c_objc_common_truthvalue_conversion.
	* c-objc-common.c (c_objc_common_truthvalue_conversion):
	New function.
	* c-tree.h (c_objc_common_truthvalue_conversion): Declare it.
	* objc/objc-lang.c (LANG_HOOKS_TRUTHVALUE_CONVERSION): Use
	c_objc_common_truthvalue_conversion.
