z80: remove remaining indirections in execute calls We now have a stable ABI that is pretty cleared up...

boot: apply BIN( to stray stable ABI references With cross compiling and IMMEDIATE words, things get icky with stable ABI references. For the same reason that EXIT, (br) and (br?) need to stay at stable offsets, these word references will not have BIN( properly applied at Inner core xcomp. The solution for now is to adjust during EXECUTE, which is ugly and inefficient, but I don't see a better solution right now.

might need to adjust addr. Ugly, but well... )

z80a: make mnemonic names more uniform across assemblers Initially, I used the same letters as those used in the z80 ref docs, but it makes the different assemblers harder to use than they should. Having consistent "argtype" rules across assemblers should help.

LDA(DE), DE INCd,
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...
