    Mark functions for optimization only on bytecode budget interrupts · 9efe315e
    Mythri A authored
    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.
