z80: small optimization in execute I had more ambitious goals, but I backed out of it: not worth it. This small optimization is an easy picking though.

L3 BSET PC ORG @ 0x34 + ! ( execute. DE -> wordref )
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.

( We don't apply BIN( reliably on stable ABI stuff, we
might need to adjust addr. Ugly, but well... )

VE: add 't' This is the first commit I do entirely in VE. It's a habit I'm planning on taking as it helps a lot to find usability issues.
