PR c/54103

	* c-typeck.c (build_unary_op): Pass original argument of
	TRUTH_NOT_EXPR to c_objc_common_truthvalue_conversion, then remove
	any C_MAYBE_CONST_EXPR, if it has integer operands.
	(build_binary_op): Pass original arguments of TRUTH_ANDIF_EXPR,
	TRUTH_ORIF_EXPR, TRUTH_AND_EXPR, TRUTH_OR_EXPR and TRUTH_XOR_EXPR
	to c_objc_common_truthvalue_conversion, then remove any
	C_MAYBE_CONST_EXPR, if they have integer operands.  Use
	c_objc_common_truthvalue_conversion not
	c_common_truthvalue_conversion.
	(c_objc_common_truthvalue_conversion): Build NE_EXPR directly and
	call note_integer_operands for arguments with integer operands
	that are not integer constants.
