  Log Message:
  -----------
  [ADT] Take graph as const & in some post-order iterators (NFC).

This patch updates a couple of functions that unnecessarily took the
input graph by value, when it was not needed. They can take the graph by
const-reference instead, which does not require GraphT to provide a copy
constructor.

Split off from D100169.
