  Reapply "[IR] `replaceUsesWith` when aliasing a GV and the use is `dso_local_equivalent`" (#220450) (#222036)

This reverts commit 751ed7b16433d2279286d0765f51cd36edc6d771.

The patch is quite indepdendent from PR #203171, which uncovered the
issue. We decouple them. The fix is tested in the unittest introduced
here. When we reland #203171, we'll add the cfi_dso_local_equivalent.ll
test.
