In CLI (but not cli-server) it's safe to assume script structures are fully immutable, given the structures will not be freed until the process ends. Hence, we can make stronger assumptions during optimization and jitting. This may be beneficial for web servers implemented in PHP, or worker mode.

In my tests, this shaves off roughly 0.5% off Symfony Demo with just opcache. and a bit less with the tracing JIT. Function JIT improves by over 4%, but is overall still slower than the tracing JIT after warmup.
