Users of this function expect alu to be a supported comparision
if the induction variable is not NULL. Since we attempt to
override the return values if the first limit is not a const, we
must make sure we are dealing with a valid comparision before
overriding the alu instruction.
Fixes an unreachable in inverse_comparison() with the game
Assasins Creed Odyssey.
Fixes: 3235a942c1 ("nir: find induction/limit vars in iand instructions")
