    [maglev] Step 1 towards ML-TF tiering · 8fc7735b

    Added IR members:
    For updating the interrupt budget: Jump, JumpLoop, Return and
    JumpFromInlined apply a delta to the interrupt budget.  For OSR:
    JumpLoop needs its loop depth and the feedback slot (where cached OSR
    code lives).
    
    This CL also adds code to maintain the interrupt budget in ML code.
    
    Future tasks are documented in TODOs.
