* recog.h (struct recog_data): New field is_operator.
(struct insn_operand_data): New field is_operator.
* recog.c (extract_insn): Set recog_data.is_operator.
* genoutput.c (output_operand_data): Emit code to set the
is_operator field.
* reload.c (find_reloads): Use it rather than testing for an
empty constraint string.
