m68k: when loading from a reference with zero extend, clear the register first, then load, instead of clearing with AND later, because this is faster on slow 68ks and also shorter

m68k: add a function to optimize const MUL cases to sequences of shifts + ADD/SUB. mainly for '000 and other low end 68ks with slow/limited MUL capabilities. inactive for now, as it wasn't that extensively tested
