  [InstCombine] Add Visited set to isOnlyCopiedFromConstantMemory()

I don't think this matters right now (because InstCombine cleans
up unreachable code early), but this will help to make sure that
we don't infinite loop once we handle phi nodes. The added test
is an example where this would happen.
