[self-interest] dynamic deoptimization (was: ARM?)

If you have a special "deployment mode" which doesn't allow the debugger
to pop up at arbitrary points so that the programmer can then single
step bytecodes from then on, then there is no need for dynamic
deoptimization.

But having explicit interpreter/development and compiler/deployment
modes is a step back to 1960s Lisp, while Self's goals are to have a
great environment for exploration while keeping the "magic" that makes
it all work hidden.
