    [snapshot] Guard against flushing when installing native IET · eec3f923
    Leszek Swirski authored
    CreateInterpreterDataForDeserializedCode checks for bytecode, copies the
    InterpreterEntryTrampoline, and installs that and the bytecode on
    InterpreterData. However, the bytecode can be flushed when the IET is
    copied, which results in a failure to read it afterward.
    
    Add an IsCompiledScope to guard against this.
    
    As a drive-by, guard against baseline code being installed on the
    function. This shouldn't happen in normal execution, but could
    theoretically happen with some extra support for --always-sparkplug.
