PPC/s390: [sparkplug][deoptimizer] Deoptimize to baseline.

Browse Source 
Port bdcd7d79d3

Original Commit Message:

    If we have baseline code, deoptimize to baseline instead of the
    interpreter. The process is similar to deopting to the interpreter.
    We just use different builtins
    (BaselineEnterAtBytecode/BaselineEnterAtNextBytecode) instead of
    InterpreterEnterBytecodeDispatch/InterpreterEnterBytecodeAdvance, that
    patch an interpreter frame to a baseline frame and continue execution in
    baseline code (based on the deopt type, at the current or next
    bytecode).
