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.
