Helper class for visiting basic blocks in dominance order.
...
It uses a worklist-based algorithm. In contrast to a recursive traversal algorithm,
it cannot cause a stack overflow for very deep dominator trees.

It does seem to make non-generic assumptions about the node
...
type, though; I had to define a WriteAsOperand function and
add a front() method to SILFunction to get this to work.
Rip out my dominators implementation and replace it with
LLVM's. I'd forgotten that LLVM's was actually generic.
