nir/lower_idiv: Use ilt instead of bit twiddling The previous code was creating a boolean by doing an arithmetic right- shift by 31 which produces a boolean which is true if the argument is negative. This is the same as the expression r < 0 which is much simpler and doesn't depend on NIR's representation of booleans. Reviewed-by: Eric Anholt <eric@anholt.net>
