    Original change's description:
    > [interpreter] Move interrupt budget from BytecodeArray to FeedbackCell
    > 
    > Interrupt budget was store in bytecode array and used to be shared
    > across all contexts. With lazy feedback allocation, using context
    > independent interrupt budget might lead to performance cliffs when
    > we have closures that do not share the same feedback (for ex: across
    > contexts). This would be a problem even earlier but it could be
    > more pronounced with feedback vector allocation, since the budgets
    > for optimization is much higher (144x) than the budget for feedback
    > allocation.
