    Reland "[sparkplug][deoptimizer] Deoptimize to baseline." · e3ccb538
    Patrick Thier authored
    This is a reland of bdcd7d79
    
    Handle lazy deopts when the current bytecode is JumpLoop.
    Instead of advancing to the next bytecode, re-execute the JumpLoop.

    Original change's description:
    > [sparkplug][deoptimizer] Deoptimize to baseline.
    >
    > 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).
