* eval.c (evaluate_subexp_standard): Add calls to binop_promote
and unop_promote before calling value_binop et. al.
* ada-lang.c (ada_evaluate_subexp): Add calls to binop_promote
and unop_promote before calling value_binop et. al.
* valarith.c (value_binop): Do not call binop_promote or unop_promote.
(value_pos): Do not call unop_promote.
(value_neg, value_complement): Likewise.
