History
Florian Hahn a12403cfea [LV] Do not consider instrs dead if used by phi that's not in plan. 
Single value phis won't be modeled in VPlan. If the phi only gets used
outside the loop, the current code misses the fact that the incoming
value is not dead. Update the code to also look through such phis to
check for outside users.

Fixes #54266
