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.

Refer to stable wordref by direct offset in "hot zone" immediates
...
Previously, it was impossible to cross-compile Collapse OS from a
binary-offsetted Collapse OS because stable ABI wordrefs would have
a wrongly offsetted address.
This solves the problem by replacing those wordrefs by direct,
hardcoded stable ABI offset references.

This will soon replace the libz80 based "forth" and
"stage" executables. This is much, much faster.
