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