  Support for link to be entirely parallelized
  
  The link job is split as such:
  
  - Front-end link
  - Back-end link
  - Independent back-end link subtasks (typically native driver compile
    jobs)
  - Post-link finalization
  
  Each step depends on the previous.  These steps are executed as such:
  
  1. Program::link calls into ProgramImpl::link
    - ProgramImpl::link runs whatever needs the Context, such as releasing
      resources
    - ProgramImpl::link returns a LinkTask
  2. Program::link implements a closure that calls the front-end link and
     passes the results to the backend's LinkTask.
  3. The LinkTask potentially returns a set of LinkSubTasks to be
     scheduled by the worker pool
  4. Once the link is resolved, the post-link finalization is run
  
  In the above, steps 1 and 4 are done under the share group lock.  Steps
  2 and 3 can be done in threads or without holding the share group lock
  if the backend supports it.  Step 2 is not yet made independent of the
  Context on some backends, and a frontend feature is used to make that
  step either run on the main thread or as a worker thread.
