[NewGVN] Add ops as dependency if we cannot find a leader for ValueOp.
If those operands change, we might find a leader for ValueOp, which
could enable new phi-of-op creation.
This fixes a case where we missed creating a phi-of-ops node. With D43865
and this patch, bootstrapping clang/llvm works with -enable-newgvn, whereas
without it, the "value changed after iteration" assertion is triggered.
