[PATCH] D13460: [IndVars] Don't break dominance in `eliminateIdentitySCEV`

[Sanjoy Das via llvm-commits]

sanjoy added a comment.

I decided to check this in and switch to a post-commit review for the following reasons:

- The fix itself is fairly simple and low-risk
- People were blocked on getting this fix in
- I didn't want to mess up the history with revert / un-revert commits
