Well, what I was thinking was we could have a section that marked all
the legitimate jump destinations. We could then vet this destination
table at load time for safe interpreters to make sure that the
destinations really were proper places to jump (i.e. real opcodes)
and then have the branch/jump ops vet their destination against the
valid destination table rather than checking every time to make sure
it's OK.
Might not be worth it, of course.
