Make word routines into word types Instead of having wordref point to core word routines, I made them into word 4 word types. It liberates space into the stable ABI and should make porting to other arches easier. I'm also thinking of combining word type with the namelen field for precious bytes saving, but not now...

z80: optimize chkPS Inline it in next and make chkPS, call a newly reserved label for it directly, removing a layer of indirection. This frees a spot in the stable ABI.

Remove LITA It was useful when we still had the relinker, but now it has no use. I was waiting a bit to see if the distinction would be useful again, but it seems like it won't.

Remove INTJUMP mechanism Not worth the trouble. Easier to set jump in binary directly.
