  -----------
  Revert "Recommit "[GlobalOpt] Pass DTU to removeUnreachableBlocks instead of recomputing.""

This reverts commit a03d7b0f24b65d69721dbbbc871df0629efcf774.

As discussed in D68298, this causes a compile-time regression, in case
the DTs requested are not used elsewhere in GlobalOpt. We should only
get the DTs if they are available here, but this seems not possible with
the legacy pass manager from a module pass.
