* ax-gdb.c (gen_expr): Handle UNOP_CAST_TYPE, UNOP_MEMVAL_TYPE.

Browse source 
* breakpoint.c (watchpoint_exp_is_const): Handle UNOP_CAST_TYPE,
	UNOP_REINTERPRET_CAST, UNOP_DYNAMIC_CAST.
	* c-exp.y (exp): Emit UNOP_MEMVAL_TYPE, UNOP_CAST_TYPE.  Update
	for changes to UNOP_REINTERPRET_CAST, UNOP_DYNAMIC_CAST.  Use
	type_exp production where appropriate.
	* eval.c (evaluate_subexp_standard) <UNOP_CAST_TYPE>: New case.
	<UNOP_DYNAMIC_CAST, UNOP_REINTERPRET_CAST>: Update.
	<UNOP_MEMVAL_TYPE>: New case.
	(evaluate_subexp_for_address) <UNOP_MEMVAL_TYPE>: New case.
	(evaluate_subexp_for_sizeof) <UNOP_MEMVAL_TYPE>: New case.
	* expprint.c (print_subexp_standard) <UNOP_CAST_TYPE>: New case.
	<UNOP_MEMVAL_TYPE>: New case.
	(dump_subexp_body_standard) <UNOP_DYNAMIC_CAST,
	UNOP_REINTERPRET_CAST>: Update.
	<UNOP_CAST_TYPE, UNOP_MEMVAL_TYPE>: New cases.
	* parse.c (operator_length_standard) <UNOP_DYNAMIC_CAST,
	UNOP_REINTERPRET_CAST>: Update.
	<UNOP_CAST_TYPE, UNOP_MEMVAL_TYPE>: New cases.
	* stack.c (return_command): Also check for UNOP_CAST_TYPE.
	* std-operator.def (UNOP_CAST_TYPE, UNOP_MEMVAL_TYPE): New
	constants.
