    PPC/s390: [sparkplug] Remove BaselineData, use Code directly · 0100a8e8

    Original Commit Message:
    
        Remove the BaselineData intermediate structure for baseline code, and
        write the baseline Code object into the SharedFunctionInfo directly. We
        still need a pointer to the BytecodeArray/InterpreterData, so re-use the
        Code object's deoptimization data slot for this (baseline code doesn't
        have deoptimization data).
    
        A consequence of this is that the BytecodeArray pointer becomes
        immutable when there is baseline code. This means that we cannot install
        a debug BytecodeArray while baseline code is active (we have to flush it
        first), and we can't tier-up code with debug BytecodeArray to baseline.
