Ok, sounds good. Ill just drop this change. Wonder why it doesnt trigger failures in MLIR itself.

Maybe it did between the two commits but we didn't notice. LLVM doesn't follow IWUY, so it could have worked because of some transitive include that got removed.

I see why it happened. This commit is before the patch D130612. I was trying to cherry pick D130612 and obviously this got missed. Thanks!
