AbstractGangTask::set_for_termination(uint active_workers) is a virtual
function that sub-classes can override to run setup code before the task
is started. The active_workers parameter tells the task how many workers
are going to execute the task.
Only a few tasks use this infrastructure and most tasks run the setup
code in the constructor or before the task is constructed. There is no
place where we construct a FlexibleGangTask task, change the number of
active workers, and then start the task. The tasks are always started
near the construction site. So, I propose that we get rid of
AbstractGangTask::set_for_termination to shrink the AbstractGangTask API.
I didn't want to change how the CMS worker threads are started, so I
moved AbstractGangTask::set_for_termination to YieldingFlexibleGangTask.
