  Log Message:
  -----------
  [Sanitizers] Remove handling for lifetimes on non-alloca insts (NFC) (#149994)

After #149310 the pointer argument of lifetime.start/lifetime.end is
guaranteed to be an alloca, so we don't need to go through
findAllocaForValue() anymore, and don't have to have special handling
for the case where it fails.
