Fixes #139023. This PR essentially removes unused global variables: - Restores the `GlobalDCE` Legacy pass and adds it to the DirectX backend after the finalize linkage pass - Converts external global variables with no usage to internal linkage in the finalize linkage pass - (so they can be removed by `GlobalDCE`) - Makes the `dxil-finalize-linkage` pass usable using the new pass manager flag syntax - Adds tests to `finalize_linkage.ll` that make sure unused global variables are removed - Adds a use for variable `@CBV` in `opaque-value_as_metadata.ll` so it isn't removed - Changes the `scalar-data.ll` run command to avoid removing its global variables --------- Co-authored-by: Farzon Lotfi <farzonlotfi@microsoft.com>
