    [compiler] Off-thread finalize each function immediately · 198deea2
    Leszek Swirski authored
    Allow "iterative" finalization when off-thread finalization is enabled,
    meaning that each compiled function is finalized immediately after
    compilation, rather than all functions being first compiled and then
    finalized.
    
    This is what we do on the main thread, and it reduces peak Zone memory
    usage by being able to discard empty compilation Zones earlier.
    
    One necessary functionality for this was being able to defer the
    finalization of asm.js functions until the main thread pause, since
    they can't be finalized off-thread -- previously we would just bail
    out of doing the off-thread finalization if any inner function was
    asm.js.
