Revert "[DirectX] Array GEPs need two indices (#142853)" and "Adjust bit cast instruction filter for DXIL Prepare pass (#142678)" (#143043)
- This reverts commit 9ab4c16042.
- This reverts commit 1d6e8ec17d.
Noticed a really weird behavior where release and debug builds have
different codegen for loads with geps after this PR. This is going to
take a minute to debug and figure out why so revert seems to make the
most sense.
