Fix debug printing of BINOP_IN, OP_OBJC_MSGCALL,
OP_F77_UNDETERMINED_ARGLIST, OP_COMPLEX, OP_OBJC_SELECTOR, OP_NAME,
OP_OBJC_NSSTRING, OP_F90_RANGE and OP_DECFLOAT.
* ada-operator.inc: Rename the file to ...
* ada-operator.def: ... here, wrap all the entries by macro OP.
* expprint.c (op_name_standard): Remove all the entries. Include
"std-operator.def" instead.
* expression.h (enum exp_opcode): Include "std-operator.def" and
"ada-operator.def". Move all the entries ...
