James Bardin 75ef61c783 check for nested module index changes
Changing only the index on a nested module will cause all nested moves
to create cycles, since their full addresses will match both the From
and To addresses. When building the dependency graph, check if the
parent is only changing the index of the containing module, and prevent
the backwards edge for the move.
