  -----------
  [LCSSA] Update unreachable uses with poison.

Users of LCSSA may not expect non-phi uses when checking the uses
outside a loop, which may cause crashes. This is due to the fact that we
do not update uses in unreachable blocks.

To ensure all reachable uses outside the loop are phis, update uses in
unreachable blocks to use poison in dead code.

Fixes #57508.
