  Log Message:
  [GlobalOpt] Fix dead const handling in pointer root user cleanup (PR61674)

Rather than cleanup up dead constant expressions as we go along,
do this once at the end. This aligns it with the
CleanupConstantGlobalUsers() implementation and avoids
any invalidation issues.

Fixes https://github.com/llvm/llvm-project/issues/61674.
