  Log Message:
  -----------
  [ArgPromotion] Add test for non-willreturn load hoisting (NFC)

In this case, we have no guarantee that the load is unconditionally
executed, so the argument promotion is not legal.

  [ArgPromotion] Don't assume all entry block instrs are executed

We should abort this walk if we hit any instruction that is not
guaranteed to transfer.
