I think turning JIT off is a valid use case, the rest looks much more
iffy. I am not sure we want to let people tell the engine to JIT certain
functions - are there a lot of cases where the engine wouldn't do it but
it's actually the right thing to do?
Don't see any use for "opcache.jit=attributes".
