*	Extract ice40_unlut pass from ice40_opt.	whitequark	2018-12-05	1	-0/+106
	Currently, `ice40_opt -unlut` would map SB_LUT4 to $lut and convert them back to logic immediately. This is not desirable if the goal is to operate on $lut cells. If this is desirable, the same result as `ice40_opt -unlut` can be achieved by running simplemap and opt after ice40_unlut.
