      [builtins] implement RunMicrotasks pump as a code stub · 52ff3ae4
      Caitlin Potter authored
      - Implement RunMicrotasks in CSA to prevent a potentially large number
        of jumps between C++ and JS code while consuming te queue. Appears to
        provide a ~60% speedup in microtask-heavy code, which from limited
        testing appears to scale linearly.
      
        The code-stub microtask pump bails out to the old C++ microtask pump
        if it encounters a CallHandlerInfo microtask, and remains in C++ for
        the remainder of the queue (returning to the JS/stub implementation
        after the bailed out queue is exhausted).
      
      - Add a variation of JSEntryStub which enters the new RunMicrotasks code
        stub.
      
      - Add a new RunMicrotasks helper to Execution, which uses the
        RunMicrotasks entry stub.
