* | Extract ice40_unlut pass from ice40_opt.whitequark2018-12-053-13/+109
| | | | | | | | | | | | | | | | 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.

* Consistent use of 'override' for virtual methods in derived classes.Henner Zeller2018-07-2016-54/+54
| | | | | | | | | o Not all derived methods were marked 'override', but it is a great feature of C++11 that we should make use of. o While at it: touched header files got a -*- c++ -*- for emacs to provide support for that language. o use YS_OVERRIDE for all override keywords (though we should probably use the plain keyword going forward now that C++11 is established)
