  [SandboxVec][BottomUpVec] Clean up dead address instrs (#122536)

When we vectorize loads or stores we only keep the address of the first
lane. The rest may become dead. This patch adds the address operands of
vectorized loads or stores to the dead candidates set, such that they
get erased if dead.
