This is a reland of f00d6a8efd
This change is significantly different from the original.
The lifetime of GrArenas on the GrSurfaceFillContext is from
first GrOpsTask creation to the completion of the first call
to GrOpsTask::onExecute. The overall lifetime of the GrArenas
is from first GrOpsTask creation until the last dtor of the
GrOpsTask.
There are checks in the GrArena to make sure that nothing is
allocated after it is removed from the GrSurfaceFillContext.
Original change's description:
> remove fAllocators from GrOpsTask
