Extract (br), (?br) and (loop)'s code out of stable ABI zone There is now no more actual code in stable ABI, only references. This makes refactoring of this code much easier. For example, changing IY to BC as the IP register.

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.

De-stabilize (br), (?br), (loop), (s) When writing the xcomp documentation, I realized that with careful threading and by accepting a bit of code duplication in the xcomp toolset, I could de-stabilize a couple of words. (n) and EXIT are a bit trickier, but I think it can be done. It would be nice to get rid of stable wordrefs...
