[VPlan] Match legacy behavior w.r.t. using pointer phis as scalar addrs. 
When the legacy cost model scalarizes loads that are used as addresses
for other loads and stores, it looks to phi nodes, if they are direct
address operands of loads/stores. Match this behavior in
isUsedByLoadStoreAddress, to fix a divergence between legacy and
VPlan-based cost model.
