Update base for Update on "[compiler] Repro for false positive ValidateNoFreezingKnownMutableFunctions"

Found when testing the new validation from #33079 internally. I haven't fully debugged, but somehow the combination of the effect function *accessing* a ref and also calling a second function which has a purely local mutation triggers the validation. Even though the called second function only mutates local variables. If i remove the ref access in the effect function, the error goes away.

Anyway I'll keep debugging, putting up a repro for now.
