We still have the problem of when is the goto_tb link initialized the *first* 
time?
Where we expect the goto_tb to fall through to stuff+exit_tb?

For i386 it's during translation, with no care for re-translation.

For ARM?  I can't see that it is.

For PPC, malc has already verified that it *never* happens.  If he
puts "trap" insns there instead of "nop" insns, he'll see the trap.
