The Func has a large number of legacy dependencies carried over from the old Standard dialect, which was pervasive and contained a large number of varied operations. With the split of the standard dialect and its demise, a lot of lingering dead dependencies have survived to the Func dialect. This commit removes a large majority of then, greatly reducing the dependence surface area of the Func dialect.
