That is, the call to it -- if operand[2] has the NOT, it should be
false, false, true instead of false, true, false.
Yes, that was my first attempt at fixing this problem, but ended up with
an unrecognized insn for the following. Which is why I switched my
approach to swapping operands in the patch.
builtin-arith-overflow-7.c:80:1: error: unrecognizable insn:
