[PATCH] D34285: [SROA] Be smarter when copying metadata to retyped loads

[Chandler Carruth via Phabricator via llvm-commits]

chandlerc added a comment.

I landed some simpler refactorings in r306267 that should be enough to implement this.

However, I noticed that SROA actually assert fails on your test case without this patch, and in a seemingly unrelated manner. I want to understand this before landing your patch (or equivalent using different API). That said, feel free to update your patch based on r306267 or I will when I finish debugging (or if you can debug the assert, let me know).

I definitely want to get this unblocked for Rust, but it seems pretty scary to paper over an assert failure. Anyways, will try to keep this moving.
