I think it would still be a good idea to pass the mode as an argument,
just in case the two other arguments are CONST_INTs (remember that
CONST_INTs don't have a mode). In fact, your proposed patch would
probably crash or just fail to do right thing should the first
argument be a CONST_INT.
However, since all uses of these instructions take a register as an
argument (and only now, after having written the paragraph above, do I
see it can only make sense to call have_add2_insn having a REG in the
first argument, I think it may indeed be ok. Then perhaps it would be
enough to check that GET_MODE (x) != VOIDmode, and abort () otherwise.
