    [Parser] Add basic support for parallel IIFE parse / compile tasks. · 85b7f1cd
    Ross McIlroy authored
    Adds support for enqueuing parallel parse / compile tasks for eagerly
    compiled IIFEs during parsing. If the --parallel-compile-tasks flag is
    enabled, the parser will pre-parse eager top-level IIFEs and enqueue a
    task on the compiler dispatcher to do the actual parsing / compilation
    on a worker thread.
    
    Currently we always enqueue the task, but we likely want to only
    enqueue parallel tasks where the script has multiple IIFEs or a
    substantial amount of top-level script code before the IIFE to avoid
    the main thread having to immediately block on the parallel task. This
    work will be done as a follow-up.
