    Original change's description:
    > Mark functions for optimization only on bytecode budget interrupts
    >
    > We used to mark functions for optimization on any interrupt. This sometimes
    > causes functions to OSR when not needed. The implementation was such because
    > we didn't have a different runtime function to distinguish bytecode budget
    > interrupts from other interrupts. For lazy feedback allocation we added a
    > new runtime function for bytecode budget interrupts so it makes it easier
    > to actually mark functions only when needed.
    >
    > This also includes a fix to reduce the stack limits for interrupts when
    > entering a scope that allows interrupts from a postponed interrupt scope.
