z80/8086: extract 2>R code from stable ABI zone Only its jump at 0x33 remains. I've also fixed a strange offset oddity in 8086's (n) placement. It was off by 2, but strangely, it ran properly. Anyway, now it's fixed.

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.
