Revert "Reland: ScopeInfo, SharedFunctionInfo never-ever serialized"

This reverts commit d3cacbbb.

>
> Changed: Fixed a test in which bytecode flushing caused a behavioral
> change between serialized- and unserialized SFI Refs. The serialized
> SFI ref kept bytecode alive while unserialized SFIs allow flushing.
> The test was fixed by adding a %PrepareFunctionForOptimization
> annotation.
