d2ec5e271c Optimize boot binary's word execution code
Should be significantly faster now. Less push/popping and usage of
DE instead of IY.

into IF, else, jump to THEN,".

add3b6629b Make DO .. LOOP binary code more compact
Only a few bytes saved in forth1.bin, but the DO .. LOOP construct
isn't used much yet. It's still significant savings per LOOP call.
